Welcom to our channel We are working with LEICA DGPS GS 14 ,1 Plus 3 1 Base , 3 Rovers We have 2 Mode s we can connect Base and Rovers 1.SIM MODE :-In this mode we can insert Sim Card and connect Base to rovers 2.RADIO Mode :- In This mode we can connect Radio frequency operating mode Base and Rovers Note:- Most of people using Radio frequency only because accuracy is good About DGPS DGPS:- Differential Global Positioning System is an enhancement to the Global Positioning System. About GNSS:-Global Navigation Satellite System (GNSS) refers to a constellation of satellites providing signals from space that transmit positioning and timing data to GNSS receivers. The receivers then use this data to determine location. About Static Mode (Control Points)survey Static GPS surveying typically uses a network or multiple baseline approach for positioning. It may consist of multiple receivers, multiple baselines, multiple observational redundancies and multiple sessions. A least squares adjustment of the observations is required. This method provides the highest accuracy achievable and requires the longest observation times; About RTK Survey Real-time kinematic (RTK) Real-time surveying technology may utilize single or dual-frequency (L1/L2) techniques for initialization, but the subsequent RTK survey is accomplished using only the L1 carrier phase frequency. Therefore, all RTK surveys are currently subject to the limitations of the L1 frequency which is 10 kilometres from the base station. In order to maintain a 2 cm level of accuracy, distances are usually considerably less than this but there may be circumstances where this maximum range may be extended. Thank for Watching G Balaji
