Applanix SmartBase
Applanix SmartBaseTM utilizes free available base stations worldwide (CORS) to generate a network of stations around the mission area. This network of stations can also be extended with customer provided stations (e.g. from other commercial providers). Within this network of stations Applanix SmartBase will estimate atmospheric, orbital and clock errors which are then used to correct for errors at the Rover location at each epoch. This post-processing method is applying the VRS (Virtual Reference Station) concept, designed to work in a mobile mapping environment.
In addition to this feature there is an Applanix SmartBase Quality Check module embedded. It allows validating the quality of the base stations (with respect to data gaps) and particularly enables a network adjustment to ensure the coordinates of all stations are homogeneous in order to achieve high accuracy.
Applanix SmartBaseTM allows to extend the maximum distance to the nearest base station to beyond 70 km and still maintain integer ambiguities, hence it beats the limitation of the 30km rule for SingleBase processing and can hence cover larger mission areas.
