IALA DGPS system
Periskal has experience in the installation and setup of an IALA DGPS system. IALA DGPS is used on the Danube and by the maritime vessels to enhance the standard GPS signal received. It provides location accuracy from the nominal 15 meter to less than 1 meter. To integrate these corrections, a vessel needs an IALA Beacon receiver on board.
A ground-based reference station is installed to broadcast the difference between the positions indicated by the GPS system and the known fixed position. The IALA DGPS network can be composed by one or more base station depending on the area to be covered. The corrections are broadcasted using longwave radio frequencies. The reference station can be connected to a central system to monitor its working status and the corrections sent.
