Abstract:	The multibase/network RTK is a part of the firmware for EuroGGD OEM boards and Legacy-E and Odessey-E receivers based on this board [1]. The RTK system provides up to 20Hz single base RTK or up to 5Hz Network RTK solutions with ambiguity estimated at 1Hz rate. Positioning is performed using dual L1/L2 bands and dual GPS/GLONASS systems pseudorange and carrier measurements. The baseses, up to three, communicate with the rover using CMR formatted corrections. Three channels are distinguished by one of the following ways: 1) when using radio modems Time Delay Multiple Acesss (TDMA ) may be used with 0, 0.333, 0.667 seconds delays for three bases respectively. 2) When using Internet connection three bases have different IP addresses. Second way has been used for our experiments.
