iMAX provides actual base station position information. VRS works so that although the rover is unaware of errors the VRS is taking care of, there still might be ionospheric remains in the base station observations. However, instead of calculating the base station observations for the provided position, or another position closer to the base station, original observation information is corrected with the calculated corrections and broadcast.

The iMAX idea, introduced by Leica Geosystems, is that networking software corrections, based on the rover’s position, are calculated as with VRS. With MAX, the network operator has to ability to transmit corrections using both two-way and broadcast communication technologies.

The MAX corrections contain the full information from the cell and therefore provide the maximum level of accuracy and reliability for the rover. With Auto-MAX even the largest reference networks can be fully serviced with a single communication channel. The auxiliaries are chosen from the surrounding stations to provide the best possible set of corrections for the rover’s position. The master station is always chosen as the station nearest to the rover. By choosing the most appropriate cell configuration, Auto-MAX corrections minimise the bandwidth required to transmit the corrections. This correction service is referred to as Auto-MAX. In the case of two-way communications, Leica GPS Spider will automatically select the optimum sites for the cell used to generate master-auxiliary corrections for each rover. Depending on the size of the network, multiple cells can be defined to optimise the transmission of data by reducing the number of stations that are contained in the correction messages.

The rover user can connect to the correction service that is most relevant for their geographic location. The VRS approach requires bi-directional communication for supplying the rover’s position to the networking software.įor broadcast communication mediums, pre-defined cells, which may be created manually by the network operator, can be used to transmit master-auxiliary corrections, known as MAX, to the rovers. Most rovers receive VRS data for a calculated base station that is within a couple of metres away. The format for sending the rover’s position is standard NMEA format. The VRS position can change if the rover is far away from the initial point. The VRS is calculated for a position, supplied by the rover during communication start-up, with networking software. The rover receiving VRS information has a lower level of these errors than a distant base station. All baseline-length-dependent errors, such as abnormal troposphere variation, ionospheric disturbances and orbital errors, are reduced for this VRS. The virtual reference station (VRS), or virtual base station (VBS), idea, introduced by Trimble, is that a base station is artificially created in the vicinity of a rover receiver.
