Differential Global Positioning System (DGPS)
Most of our aircraft are fitted with differential GPS AG-NAV2 technology. A differential GPS monitors the GPS satellite signals, calculates corrections and transmits this corrected ‘differential’ information to the AG-NAV2 DGPS receiver. The AG-NAV2 DGPS system can receive signals ten times per second from up to 25 different satellites. A minimum of 4 satellites are necessary to obtain a good position fix. Accuracy therefore is within 1 metre ensuring compliance with spreading instructions, and compliance with environmental requirements. For those farms that have already been GIS mapped, the pilot simply loads the GIS map into his GPS and starts work straight away, rather than fly the boundaries first.
Fletcher Forests emailed a map
of the forest area to be covered to the Super Air pilots who downloaded it to their GPS system. They then set out to spray 35,000 hectares of featureless forest with an accuracy of within 1 metre. For farms that don’t have GIS maps of their farms, the pilots fly all the corners of the job first to register them into the GPS before sowing.
If Super Air spreads your fertiliser it won’t be wasted.
Super Air is the only New Zealand agent for AG-NAV. If you are interested in this technology please email us on reception@superair.co.nz or phone 07 843 6066.
 Differential Spreading using GPS driven technology
To further increase accuracy, Super Air is trialling a differential spreading system which is linked to the AG-NAV2 GPS and ensures differential spreading of fertiliser automatically by varying the hopper apertures as the aircraft passes pre-recorded GPS points on the farm map. This technology permits the spreading of different rates of fertiliser during one flight path which will ensure optimum nutrient management.
