The satellite state vector, satellite clock and receiver clock parameters are estimated using consolidated orbit determination algorithm of Navigation software installed at ISRO Navigation Center. The estimated state vectors are converted into the Keplerian elements. The variations in the Keplerian elements...
Three IRNSS satellites are currently operational: two inclined geosynchronous orbit (IGSO) satellites, PRN 1 (1A), PRN 2 (1B); and one geostationary satellite, PRN 3 (1C) launched on October 16, 2014. Seven satellites will comprise the full constellation, which is expected to be complete in...
"India's third navigation satellite is up in the orbit", said ISRO chairman K Radhakrishnan after the launch. Initially, the satellite was scheduled for launch October 10, but was put off by a week due to a glitch in the telemetry system.IRNSS-1C is the third out of seven in the ...
The data of I1, I2 and I3 are used by [5] for comparison of the orbit determination methods, and by [6] to validate the orbit accuracy with modernized ephemeris parameters. The first positioning results based on the data of I1, I2, I3, and I4 over India are presented in [7], ...
