Space Norway will cooperate with the satellite operator Inmarsat and the Norwegian Ministry of Defence to offer mobile broadband coverage to civilian and military users in the Arctic. Two satellites will be built by Northrop Grumman and are scheduled to be launched by SpaceX in late 2022. The ground station will be established in North Norway and ensure Norwegian control of this critically important capability.

“This will be a milestone for people in the Arctic who have very limited or no broadband access in the region” says Jostein Rønneberg, Space Norway ́s CEO.“We are building a robust communications capability in an area strategically important to Norway and our partners. This will be vital for surveillance, fishery control and rescue operations in the vast sea area that is under Norwegian control, and will significantly improve our ability to operate in the High North”.

Space Norway, a limited liability company owned by the Norwegian government, has established a new subsidiary company, Space Norway HEOSAT AS, to manage the program and operate the two satellites together with Kongsberg Satellites Services in Tromsø, Norway. The program is fully financed with customer agreements in place for the service life of the satellites.

“After a multi-year dedicated effort, we are both proud and happy to have closed customer agreements with Inmarsat and with the Norwegian and US militaries”, saysthe Program Director Kjell-Ove Skare. “This is an exciting collaborative effort, which ensures a cost effective solution for all parties. Now we are eager to start the real work of building the satellites and the ground stations. We look forward to providingthe world’s first and only mobile broadband service in the Artic region; somethingwhich has long been an important objective for the Norwegian authorities.”

Both satellites will be launched in late 2022 on a SpaceX Falcon 9 rocket into a Highly Elliptical Orbit (HEO), which will provide full coverage from 65 degrees North,

which in practical terms is the area North of the Arctic Circle. Each of the two satellites will carry multiple payloads, and the system is scheduled to be operational for at least 15 years with users able to switch between current geostationary satellites and the HEO satellites. Each satellite will have a mass of 2000 kg and provide 6 kWatt power through their sun arrays.

So I have some questions about this Space Norway launch.  I don't have a subscription to PBdeS's web site so maybe someone who can read it might get more information:

This launch is using Inmarsat's old contract with SpaceX?  The tweet said Space Norway got the launch through Inmarsat.

63 degrees is in that tweener region between Cape Canaveral and Vandenberg.  Which site is the more likely location for the launch?

I believe these will be in 90 degree inclination orbits.  Essentially hovering over the north pole at apogee to cover the entire arctic north of ~63 degrees.  So either Vandenberg or south from Cape Canaveral if that option becomes available.

Their FCC documentation said 63.4 degree orbit.

Isn't that a classical Molniya orbit? Wow, I think this is the first commercial Molniya orbit comsat that is not from Russia!

For NRO Molniya orbit payload both the Cape and Vandenberg have been used, although Vandenberg seems to have been used more in recent years (NRO L-35/42).

[Northrop Grumman] Arctic Satellite Broadband Mission Satellite System demonstrates Northrop Grumman’s integrated approach to mission success

Dulles, Va. – July 3, 2019 – Northrop Grumman Corporation (NYSE: NOC) has been awarded a contract by Space Norway to deliver its Arctic Satellite Broadband Mission (ASBM) system. Northrop Grumman will design, manufacture and integrate two satellites in addition to providing critical ground infrastructure.

The ASBM satellites will carry multiple hosted payloads including an X-Band payload for the Norwegian Ministry of Defense and a Ka-Band payload for Inmarsat. Northrop Grumman announced last year that it will also provide two Extremely High Frequency eXtended Data Rate (EHF XDR) payloads for the Enhanced Polar System-Recapitalization (EPS-R) to the U.S. Air Force for integration on the spacecraft. The systems are designed to improve secure and continuous communications in the North Polar Region. Additionally, Northrop Grumman was selected to provide critical ground infrastructure for EPS-R.

“This contract award marks our first mission with Space Norway and we appreciate the confidence they have in our capabilities to deliver high quality communication satellites,” said Frank DeMauro, sector vice president and general manager, space systems, Northrop Grumman. “By using our flight proven GeoStar platform coupled with our end-to-end payload integration capabilities, we are eager to demonstrate our ability to provide innovative solutions that regularly exceed our customer’s mission needs.”

ASBM’s satellite system will be designed, built and tested at Northrop Grumman’s state-of-the-art satellite manufacturing facility in Dulles. The satellites will be based on the company’s proven GEOStar platform which has been integrated on more than 40 spacecraft. ASBM is scheduled for a dual launch in late 2022.

Space Norway was established in 2014 as a limited liability, governmentally owned company.

Northrop Grumman is a leading global security company providing innovative systems, products and solutions in autonomous systems, cyber, C4ISR, space, strike, and logistics and modernization to customers worldwide.

This is not a Molniya orbit.

The orbits are related in that each is highly eccentric.  In each orbits the satellite remains fairly stationary near apogee for most of the orbit, and multiple satellites are needed for continuous coverage.

However a Molniya orbit has an inclination of 63 degrees and serves a circle centered on a point 63 degrees north touching the pole on one edge and perhaps 45N on the opposite side.  it does not cover the entire arctic.  In contrast a polar orbit would serve the area of the arctic circle centered on 90 degrees north.

Also because the service area from a Moliniya is not centered on the pole the parameters of the orbit must be chosen so the orbit is Geo-synchronous and the apogee returns to the same spot.  So a Moliniya orbit is fairly specific.  On the other hand any high eccentricity polar orbit can serve the arctic because of rotational symmetry around the pole, geo-synchronous is not required.

I believe your description is incorrect.
A Molniya orbit is a12 hr orbit at the 63 and a fraction degree inclination where the rate of rotation of the line of apsides goes to zero. That way the apogee, which is set at the northernmost point, stays there, rather than rotating away.
But they are only at 63 N for a moment, and then go to 63 South, once per orbit.
If a satellite is at any higher (or lower) inclination, including 90 degrees, then it’s apogee will roll around the orbit. That won’t serve the purpose of remaining high in the sky for extended fractions of a day.
These orbits are not “geosynchronous”. They move across the sky and must be actively tracked.
But one of a pair it trio is always above the horizon and they’re a lot closer than GEO.

First, I agree with Comga; Barley's description of Molniya orbit is different from what I remember from Orbital Mechanics (which I passed with "A", but some 20+ years ago).

Second, about the orbit itself:
Space Norway says in their press release it will be - Highly Elliptical Orbit with 43000 km Apogee and 8000 km Perigee. Which does not fit Molniya's semi-major axis.
Also, SpaceNews in this article
https://spacenews.com/northrop-grumman-to-build-two-triple-payload-satellites-for-space-norway-spacex-to-launch/
says the orbit is UNIQUE.
Finally, FCC filing says the inclination will be 63.4°.
So, if everything above is correct, it is going to be a "Molniya-like orbit" - with high eccentricity and same inclination, BUT with different orbital period.
If (again) the apogee and perigee numbers are correct, the period will be 941.6 min, or approx 0.66 of sidereal day.
Which is remarkably close to 2/3 (0.666...)
Satellite in Molniya orbit appears above northern hemisphere twice per day, first around "N" latitude and second around "N+180" latitude (and this is why the same sat in Molniya orbit CAN in fact serve ALL northern regions - but not at the same time).
Satellite in this ASBM-Molniya-like orbit will appear above northern hemisphere three times per two days - in points spaced by 120° by latitude.

Third, about launch site:
63.4° inclination can be reached directly from VAFB. From Cape there is an option to launch ASBM satellites into "transfer orbit", something like 400 km x 43000 km @ 57.5° inclination. In this case satellites have make apogee burn for perigee raising AND gaining remaining 6° to inclination. At this height - 43000 km - it should not take a lot of delta-V. Atleast in 2004 Quasar-15 (launched by Atlas-IIAS from Cape) did the same trick.
Another option for launch from Cape is a "dog-leg", for which Falcon 9 will probably have enough performance since the total payload is about 4000 kg.

Edit - corrected typo.

The satellites are called ASBM (Arctic Satellite Broadband Mission). Perhaps someone can rename the thread.

Te orbit is called Tundra Orbit, a sibling of Molnyia but geosynchronous, it goes over a single point rather than two.

That doesn't seem right
It is related to the Molniya orbit, with that special inclination.
But as smoliarm said, it appears (hovers briefly) "over" three different spots around the north pole.
It is NOT geosynchronous is the classical sense that it doe not remain synchronized with the earth's motion at all times.
It's ground track loops around the world.
That ground track does repeat with a period of three days.
(If having an integer number of days between repeat cycles made it "geosynchronous", then ALL orbits would be geosynchronous, just with number much larger than one.)

(Ha, smoliarm!  I think I passed Orbital Mechanics 401 some 30+ years ago, but can't remember my grade.)

Go and check Tundra orbits and Japan's QZSS. The reason it is 2/3rd of a day is to be able to put 3 satellites to give continuous coverage at very high inclinations. The racetrack wrt fixed-Earth reference frame is fixed, it looks like an elongated 8. So I do consider it geosynchronous, just not at 1:1. I very specifically said geosynchronous and not geostationary.
Molnyia can be made to have two or three peaks in it's Earth-fixed racetrack. Northern Hemisphere users obviously prefer the 2 peaks. But I've always speculated about a 3 peak Molnyia for the Southern Hemisphere so Argentina, Chile, Australia, NZ and South Africa could have communications close to their antarctic bases. Regrettably you'd need 12 birds for that.

Ok, once again, I've passed exam in Orbital Mechanics a LONG time ago.
Therefore it's possible I forgot something important.
However, here is what I seem to remember, in somewhat random order:
1.
Tundra orbits BELONG to the type called "geosynchronous"
2.
All Geosynchronous orbits have orbital period STRICTLY EQUAL to Earth's sidereal period (which is 24 hrs minus ~ 4 min, IMSMR). Therefore, All Geosynchronous orbits have STRICTLY defined semi-major axis, which one can calculate from 3d Kepler's Law.
3.
Tundra orbits include those geosynchronous orbits with inclination of ~ 63°

Now, on this particular orbit for Space Norway satellites:
If we assume the apogee (43000 km) and perigee (8000 km) reported by company ARE correct -
- then this orbit DOES NOT belong to Tundra family, nor it belongs to Molniya orbits.

And one more thing on *orbit names* - (again, IIRC) -
Let's denote satellite period as *Ts* and planet rotation period as *Tp*.
Now, if the ratio Tp/Ts can be represented by some (small) INTEGERS - then such orbit will be called *Phase-Locked*
In other words:
GEO = Phase-Locked with Tp/Ts of 1:1
Molniya = Phase-Locked with Tp/Ts of 2:1
"Space Norway orbit" = Phase-Locked with Tp/Ts of 3:2

Launch of Arctic Satellite Broadband Mission (ASBM) satellites delayed from late 2022 to early 2023:

USSF’s EPS-R Program on Schedule for Historic Polar Mission [dated Oct. 29] (bolds mine)

Quote
LOS ANGELES AIR FORCE BASE, Calif. -- A unique partnership with Norway and the U.S. Space Force’s Space Systems Command will extend satellite communications for U.S. polar forces and save taxpayers millions of dollars.
 
SSC’s Enhanced Polar Systems-Recapitalization (EPS-R) program successfully completed the ready-to-ship review at the end of September for the first of two payloads to begin the integration process onto Space Norway’s space vehicles.
 
EPS-R is an Extremely High Frequency (EHF) MILSATCOM system designed to extend EPS (legacy) services into the early/mid-2030s. Its mission serves to provide 24/7 protected satellite communications for U.S. polar forces operating in the Arctic region.
 
<snip>
 
Using a host space vehicle like Space Norway means it is imperative the SSC team meets its scheduled deadlines to coordinate with Space Norway, Philichi said. The second payload is expected to hit its ready-to-ship milestone just before Thanksgiving.

<snip>

Hosting the EPS-R payload on the Norwegian Artic Satellite Broadband Mission (ASBM) is projected to save the USSF more than $900 million dollars, and deliver Satellite Communication capability to the polar region three years faster than a traditional satellite acquisition program.
 
“Norway is a key U.S. ally in the polar region, and because of technology mitigation, the technical risk is low for integrating a National Security Space payload on their Arctic Satellite Broadband Mission (ASBM),” Leach noted.
 
By January 2022, EPS-R plans to have both of its Northrop Grumman-built payloads complete. The program is on track for a dual launch with Space Norway scheduled for early 2023.
