What is GLONASS?

What is GLONASS? Short for Global Navigation Satellite System, GLONASS is a Russian satellite-based navigation system that works alongside GPS (Global Positioning System) to provide position information to compatible devices.

How does GNSS jamming technology work?

GNSS jamming technology would disable the offender tracking bracelet. Jammers work by flooding the front end of the SatNav receiver or GNSS based tracking device with too much power. The native GNSS signal when broadcast from the satellite is equivalent to a 20 Watt light bulb 12,000 miles away.

What are the different types of GLONASS signals?

GLONASS satellites transmit two types of signal: open standard-precision signal L1OF/L2OF, and obfuscated high-precision signal L1SF/L2SF. The signals use similar DSSS encoding and binary phase-shift keying (BPSK) modulation as in GPS signals.

Why do GPS navigation devices need GLONASS?

Manufacturers of GPS navigation devices say that adding GLONASS made more satellites available to them, meaning positions can be fixed more quickly and accurately, especially in built-up areas where buildings may obscure the view to some GPS satellites.
