    • 10:00 (IST)

      Troll station has established connection with the vehicle. All the 104 satellites have been injected. Isro now holds the world record in the number of satellites deployed in a single launch. The mission has been successful. 

    • 09:59 (IST)

      All the satellites have now been deployed, if everything has gone according to plan. Isro is waiting for confirmation from Troll station in Antartica. 

    • 09:58 (IST)

      The PSLV-C37 mission has an unprecedented number of separation events.

      There are 8 Lemur satellites on board by Spire Global. 

    • 09:55 (IST)

      The total mass of the 88 satellites belonging to Flock-3p by Planet Labs weighs 569 kg along with the quadpack. 

    • 09:54 (IST)

      About two minutes left for the separation of the final nanosatellites. The Troll station will establish connection in about two minutes as well. 

    • 09:52 (IST)

      Two Dove satellites of Planet Labs being released from the International Space Station. There are 88 of these on board. Isro's launch will allow Planet Labs to image the earth every day, with a constellation of 100 satellites. The remaining 12 satellites in the constellation were launched by Isro in the PSLV-C34 mission. 

    • 09:49 (IST)

      There will be no signal from the vehicle for about six minutes, as the tracking is being handed over from Mauratius to Antartica. The nanosatellites will be seperated during that time. The data will be recorded on board, and we will know if any problems has happened after the Troll station in Antartica establishes connection with the launch vehicle. 

    • 09:47 (IST)

      The nanosatellites are being deployed. 

    • 09:46 (IST)

      The CartoSat-2 series satellite has been seperated, along with INS-1A and INS-1B. All Indian satellites have now been launched. 

    • 09:45 (IST)

      Fourth stage has been cut off. The orbit and inclination has been achieved. The CartoSat-2 series satellite will be injected into orbit in about twenty seconds. 

    • 09:45 (IST)

      The flight parameters are normal. Facilities in India, Mauratius and Antartica are tracking the flight at different points. 

    Isro plans to launch a world record of 104 satellites on a single Polar Satellite Launch Vehicle on 15 February 2015 at 9:28 am. The main payload is the indigenous Earth Observation Satellite, CartoSat-2D. The remaining co-passengers are all nanosatellites, mostly based on the CubeSat standard. There are 88 satellites on board from Planet Labs, which is a record in itself as the most number of satellites of a single constellation deployed at once.

    The nanosatellites are piggybacking on a launch meant primarily for the CartoSat-2D, and Isro is using it's "workhorse" launch vehicle to its full capacity. The commercial arm of Isro, was responsible for getting the nanosatellites on board, and more than half of the mission cost will be recovered because of the foreign satellites.

    The live cast may use some unfamiliar terms and short forms, so here is a small primer.
    PSLV - Polar Satellite Launch Vehicle, India's most reliable rocket.
    XL - A configuration of the PSLV that has six additional strap on motors. The launch vehicle is then designated as PSLV-XL. If the rocket is used without the strap on motors, it is called the PSLV-CA variant, the CA stands for Core Alone.
    CubeSat - an easily configurable nanosatellite platform that was originally developed for academic purposes.
    INS - Isro Nano Satellite, an indigenous standard similar to the CubeSat
    SDSC - Satish Dhawan Space Centre, India's main rocket launching facility. India still launches sounding rockets from its first launch facility, Thumba Equatorial Rocket Launching Station (TERLS).
    SHAR - Sriharikota High Altitude Range, the particular facility in SDSC that launches rockets. Often used interchangeably with SDSC.
    FLP - First Launch Pad, the launch pad being used for the PSLV-C37 mission. There are two active launch pads at SDSC, and a third one is planned.
    SSO - Sun Sychronous Orbit is an orbit where satellites pass over a point at the same time every day. This orbit is particularly useful for imaging the earth, as it offers consistent lighting across many passes. A mid morning pass is ideal as it has the least amount of shadows.
    Isro - Indian Space Research Organisation
    Antrix - The commercial arm of Isro, responsible for getting marketing India's launch services. Antrix negotiated the deals to get the 101 foreign satellites on board.
