The Differences Between GPS and GLONASS
Now that we have an idea of how the system works and what we need for tracking, let's compare GPS with the Russian GLONASS system. For GPS, the US has committed to maintaining at least 24 operational GPS satellites, 95% of the time. In the past few years 31 satellites have been steadily operational. The GLONASS constellation was also completed in 1995, but at the end of the 1990s became incomplete with the loss of satellites. Under Vladimir Putin’s presidency the GLONASS project was made a priority and received a substantial increase in funding. By October 2011 the full constellation of 24 satellites was restored, giving global coverage. In terms of positional accuracy GPS is slightly better than GLONASS overall, but due to the different positioning of the GLONASS satellites, GLONASS has better accuracy at high latitudes (far north or south).
