WebJul 8, 2010 · This would ideally be determined in an environment with little or no multipath or attenuation. Differential GPS (DGPS) can also be used in such environments if the reference station data is available. DGPS increases the accuracy of the initial positions and consequentially all the following positions if determined relatively by Doppler positioning. WebTwo numbers exits: 1. GPS reference station number and 2. DGPS broadcast station number (Table 3.2). The numbers itself are not part of the RTCM standard, but are assigned by IALA [3]. Some authorities stick to the RTCM standard and send the reference station number, others use the broadcast station number. DGPS – 4 –
