Benefit of Complete State Monitoring For GPS Realtime Applications With Geo++ Gnsmart

Today, the demand for precise positioning at the cm-level in realtime is worldwide growing. An indication for this is the number of operational RTK network installations, which use permanent reference station networks to derive corrections for distance dependent GPS errors and to supply corrections to RTK users in realtime. Generally, the inter-station distances in RTK networks are selected at several tens of km in range and operational installations cover areas of up to 50000 km x km.
