Three new GLONASS satellites were launched last December 14. Their orbital slots or PRN numbers are: 01, 04, 05. Number 05 (R05) has been declared operational on January 10 (see the GLONASS constellation status).

Since version 2.0 magicGNSS is able to calculate GLONASS satellite orbits and clocks using the Orbit Determination & Time Synchronization algorithm (ODTS). 15 Russian satellites can currently be processed in ODTS, from a total of 16 operational ones (R19 cannot be processed because it only transmits in L1). The following plots show our GLONASS orbit and clock estimation accuracy (actually precision or internal consistency), from comparing overlapping ODTS arcs.
