ISAC Director. Cartosat 2E in April (not sure if that is the launch date or when the satellite is ready).

That's all for my play-by-play coverage.

I'm going to get some shut-eye, so have a good night.

I'm not surprised; the ISRO officials voluntarily made the decision to exclude Sri Lanka from the map.
I have noticed it before too. But its an old software from the 90s by the way. Perhaps they thought then that depicting Sri Lanka so close to the flight path would create a clutter.

Having added up the satellite masses as listed in the launch brochure, I got a total payload mass of 1,196.8 kilograms rather than the advertised 1,378 kilograms.

What's with the extra 181.2 kilograms?

I think this represents the mas of the Quadpack's and the deployment controllers. On the website from ISIS_Launch service, the mass of a Quadpack is reported to be 7,5kg.
25 x 7,5kg = 187,5 kg.

For those interested: @dovesinspace

PSLV-C37 Successfully Launches 104 Satellites in a Single Flight

Quote
In its thirty ninth flight (PSLV-C37), ISRO's Polar Satellite Launch Vehicle successfully launched the 714 kg Cartosat-2 Series Satellite along with 103 co-passenger satellites today morning (February 15, 2017) from Satish Dhawan Space Centre SHAR, Sriharikota. This is the thirty eighth consecutively successful mission of PSLV.  The total weight of all the 104 satellites carried on-board PSLV-C37 was 1378 kg.

PSLV-C37 lifted off at 0928 hrs (9:28 am) IST, as planned, from the First Launch Pad.  After a flight of  16 minutes 48 seconds, the satellites achieved a polar Sun Synchronous Orbit of 506 km inclined at an angle of 97.46 degree to the equator (very close to the intended orbit) and in the succeeding 12 minutes, all the 104 satellites successfully separated from the PSLV fourth stage in a predetermined sequence beginning with Cartosat-2 series satellite, followed by INS-1 and INS-2.  The total number of Indian satellites launched by PSLV now stands at 46.

After separation, the two solar arrays of Cartosat-2 series satellite were deployed automatically and ISRO's Telemetry, Tracking and Command Network (ISTRAC) at Bangalore took over the control of the satellite. In the coming days, the satellite will be brought to its final operational configuration following which it will begin to provide remote sensing services using its panchromatic (black and white) and multispectral (colour) cameras.

Of the 103 co-passenger satellites carried by PSLV-C37, two – ISRO Nano Satellite-1 (INS-1) weighing 8.4 kg and INS-2 weighing 9.7 kg – are technology demonstration satellites from India. 

The remaining 101 co-passenger satellites carried were international customer satellites from USA (96), The Netherlands (1), Switzerland (1), Israel (1), Kazakhstan (1) and UAE (1). 

With today’s successful launch, the total number of customer satellites from abroad launched by India’s workhorse launch vehicle PSLV has reached 180.

It seems that the DIDO-2 satellite has a second name.

Wow that cubesat deployment goes fast. Most likely the video is played at a faster then normal speed.

Also the cubesat's that have been communicating, according to: @Dovesinspace, ISIlaunch and @Spire
Signal aquisition of Lemur-2's, BGUSat and Al-Farabi-1 are unknown, to me.

Edit: Doves are Flock 3P satellite ...

Celestrak may have to make a separate entry for  130  ( 104 satellites + Launch adapter/4th stage  + 25 Quadpack enclosures  ) objects from this flight.

( A doubt ..  Are quadpacks also released or do they keep attached to the launcher? )
