It may already be somewhere, I have not found it.

OneWeb low Earth orbit satellites are designed to provide consumers on the ground with the high-speed Internet directly through satellite communications. The orbital constellation will consist of 18 planes with 36 satellites in each. The satellites are planned for launches from Baikonur, Vostochny, and from the Guiana Space Center (GSC).

That makes 648 satellites.
My question: How are the 18 planes arranged?
Like that? plane 1: rel. RAAN 0°; plane 2: rel. RAAN 10°; ... plane 18: rel. RAAN 170°
Then in the opposite direction between plane 1 and 18.

Thanks in advance.

Launches are cool, but we get just as excited seeing our Alaska Gateway Antennas installed! This gateway will provide connectivity in the most remote regions of Alaska.

Next flight of satellites to Baikonur in the January 12-22 timeframe.

Recent Arianespace schedule for 2020 posted in other threads shows availability of 8+ Soyuz from Baikonur/Vostochny, 2 Soyuz from Kourou, and one Ariane 6 from Kourou this year depending on satellite availability.

Autonomous Vehicle Traffic Jam! Two K-9's figuring out who goes first as they move satellites between testing stations (LOT's of testing). 🛰️🛰️Congrats to the @OneWebSatellit1 team for building such an amazing automated factory! 🛰️🛰️

Great day @OneWebSatellit1 and thanks for hosting the Florida contingent of @StanfordOnline high school students (including my kids 🙂)! The factory is full and bustling - now producing 2 satellites per day for the launch campaign! Such cool automation.

Presser:

OneWeb and SatixFy to launch a digital technology pathway payload in 2021

Payload includes Beam Hopping, On-Board-Processing and Digital Beam Forming
Enables right-sized constellations for maximum efficiency

London and Farnborough, UK – 13 January 2020: OneWeb and SatixFy UK today announce plans to add a digital technology pathway payload that will include a full digital payload into OneWeb’s launch schedule during 2021.

This new technology will pave the way for satellites with a higher level of flexibility to efficiently support peaks in demand without oversizing the constellation.

The digital-transparent payload will demonstrate full Beam Hopping capability in both Forward and Return Links. It will include an On-Board-Processing subsystem capable of running independent links on the User and Gateway links on the ground with different capacities. Electronically Steered Multi-Beam Antenna with True Time Delay beam-forming, capable of pointing and switching multiple beams to multiple directions simultaneously are an additional major feature.

This combination of features enables significantly higher throughput to designated areas within satellite coverage, while continuing to meet all national security concerns.

Active areas are dynamically allocated much higher capacity than areas that do not require as much bandwidth and are just being scanned to gauge demand.

The Beam hopping capability also enables seamless handover for mobile devices, between beams and satellites. An example would be an Aero terminal for In-Flight Connectivity, able to operate on both LEO and GEO simultaneously and maintaining make-before-break connectivity between the rising and setting satellites. Maximum capacity can be directed from multiple sources to hot-spots like busy airports.

Advanced discussions are in progress for collaboration and support from the European Space Agency and the UK Space Agency.

“We have designed several chip sets across the full satellite value chain including terminals, payloads and gateways, creating a full eco-system based on our own software”, said Yoel Gat CEO of the SatixFy Group. “This new OneWeb satellite will demonstrate all of these capabilities.”

“This leading-edge satellite will be fully operational and is a great opportunity to showcase what can be delivered with our payload technology”, said Massimiliano Ladovaz, Chief Technical Officer at OneWeb. “The improved performance, greater efficiency and targeted capacity, together with sophisticated ground infrastructure, puts us at the forefront of LEO communications network services.”

OneWeb launched its first satellites in February 2019 and will shortly start a regular launch program to deliver global commercial broadband services at the end of 2021.

So, it appears that each plane shipment has 2 containers with 8 satellites per container. The two shipments have landed in Russia on December 17th and January 17th. That puts current satellite shipping rate at 1 every ~2 days or 25% of their target rate of 2 satellites per day.

On January 17th there are 4 containers with a total 32 satellites arrived. (container 7, 8, 9 and ?)

In December most likely 16 in 2 containers. ( container 1 and 6 )
