What’s the status of GLONASS?
I said in 1996 that interest in GLONASS would increase in the States since Ashtech (now Thales Navigation, Santa Clara, Calif.) had announced a single board receiver that integrates GPS and GLONASS. The Ashtech receiver has the ability to receive signals from both constellations. Since that time, other receivers have appeared on the market capable of integrating GPS and GLONASS, notably Topcon (Topcon Positioning Systems, Pleasanton, Calif.) and Javad. In my community firms using GPS/GLONASS receivers for real-time kinematics (RTK) are picking up three or four GLONASS satellites along with eight to 10 GPS satellites.
