Will you use GPS for my survey?

We may use a satellite receiver during the course of our work. The United States’ Global Positioning System (GPS) consists of up to 32 medium Earth orbit satellites in six different orbital planes, with the exact number of satellites varying as older satellites are retired and replaced. The GPS system has been operational since 1978 and is currently the world’s most utilized satellite navigation system. In actuality, Herrick & Salsbury, Inc., utilizes GNSS receivers (GNSS stands for Global Navigation Satellite System and is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage). Our survey grade receivers utilize multiple satellite positioning systems including GPS, GLONASS (Russian), Galileo (European), and Beidou (Chinese), resulting in the most accurate positioning.
