VERIPOS provides complete, global, dual-beam coverage through our network of over 80 stations, transmitting on seven L-band satellites.

Station network

All our GNSS reference stations are housed in secure locations equipped with dual redundant systems and back-up power. Diverse communications are also employed at the reference stations, with a minimum of two separate communication links for each site. Stations are controlled from our fully redundant Network Control Centres (NCCs) with a 24-hour response system available at each reference site.

Service distribution

Operating on seven independent global satellites ensures clients have access to a minimum of two sources of VERIPOS augmentation services at any global offshore location. Land Earth Stations (LESs) for each satellite are chosen to ensure that no geographic region has beams uplinked from the same LES.

Quality of service

Both NCCs feed primary and secondary data streams to the LES via duplicate, physically diverse communication lines. If a problem arises, these data streams are fed into hierarchical switching.
