    2006

    2006

    ADQ1

    – by far, the most advanced Wireless Pilot Plug connector at that time. The purpose of the product is to bridge AIS information from the pilot plug of the vessel and to the pilot’s laptop via WLAN.

    ADX PPU

    2005

    ADX PPU

    – the first portable navigation system designed for Pilots (PPU) based on GPS/GLONASS L1/L2 RTK, giving 1 cm positioning and speed performance. Also equipped with high-end Fiber Optic Gyro, the ADX PPU was the first ever PPU working sufficiently accurate and reliable in accordance to the demanding specifications of the Dutch Pilot Organization. ADX is approved by Dutch authorities and mandatory for pilots when the biggest vessels are approaching Dutch ports.

    2004

    2004

    DC200 RTK system

    –the first GPS/GLONASS L1/L2 RTK receiver for maritime positioning. Reliable positioning at 1 cm level. The DC200 system has since release been supplied to many Hydrographers and major Dredging companies such as Boskalis, Dredging International and Van Oord.
