JMT has eight dual frequency GPS receivers, capable of performing static, fast-static or real time kinematic (RTK) surveys. GPS surveys can be performed as a quick and cost-effective way of establishing survey control for specific sites, setting first-order control for various public agencies, control panels for aerial photography, or data collection. JMT is using the GPS+ system (GPS plus other constellations including GLONASS) to provide X, Y & Z coordinates for specific state and local datums.
