AXIO-NET PED - The Precise Real-time Service Providing a Measuring Accuracy of +/- 2 cm

AXIO-NET provides all over Germany standardized correction data for GPS and GLONASS positioning with the highest accuracy in real-time. Without any additional system components you can easily and reliably determine your position with an accuracy of +/- 2 cm with two-frequency receivers offered by all known producers

The precise real-time service (PED) supplies measurement accuracies of up to 2 cm in the position and 4 cm in the height which can be obtained with geodetic two-frequency receivers. This is made possible by the individual application of a network of more than 150 reference stations all over Germany which can be reverted to when satellite signals are to be corrected. Thus, essential errors of satellite signals can be modelled and corrected. They mainly refer to clock errors, satellite orbital errors and runtime errors due to ionosphere and troposphere.

Individual correction data are calculated for each user; these data are returned in a standardized format (RTCM) to the user. The clock rate is 1 second. The original GNSS signals are corrected by means of the AXIO-NET data in the satellite receiver of the user.The data transfer between the mobile positioning systems and the AXIO-NET computer centre is performed via mobile connection (GSM or GPRS). Based on the data delivered by the reference stations, correction models are calculated and are made available to the user who transmits first of all his approximate position in the standardized NMEA format.

For this purpose a virtual reference station (VRS) is optionally calculated. The errors having systematic effects are eliminated completely by means of the correction model.
