We used to divide GPS receivers into consumer grade, resource grade and survey grade. Have these categories been replaced by a continuum of GNSS capabilities?
Clem Driscoll
“In the U.S. commercial telematics market, GPS remains the primary source of location data, with very little reliance on other GNSS networks. A bigger issue is the generation of cellular networks used to transmit GPS data, with 3G network sunsets pending and 5G on the horizon. As autonomous commercial vehicles become closer to a reality, multiple GNSS networks and differential techniques will become essential. These solutions are currently in development.”

“No. These categories still define important hardware distinctions (such as antenna) and required correction services that define the achievable specifications. Although they all have correlators, they have very different architectures; however, resource and survey have a blurrier line.”
