Preliminary performance evaluation of IRNSS-GPS-SBAS receiver in terms of position accuracy and velocity
The positional accuracy of navigation receiver is an important factor for various applications. Based on the application, the achieved positional accuracy levels vary from meters to millimeters. IRNSS-GPS-SBAS (IGS) receiver is capable of receiving all the seven IRNSS satellite signals in L5 (1176.45MHz) and S1 (2492.028MHz) band in addition to twelve GPS satellite signals and two SBAS (GAGAN) satellite signals in L1 (1575.42 MHz) frequency band. In this paper the position accuracy is evaluated in terms of 2DRMS, 3DRMS CEP, SEP, Geometric Dilution of Precision (GDOP) and Doppler shift in various modes namely Hybrid (IRNSS L5 and GPS L1), IRNSS dual frequency (L5 and S1), IRNSS L5 only and IRNSS S1 only mode. In Hybrid mode, it is found that all the positional accuracy values are better than the corresponding other mode values.
