The Electronic Navigation Research Institute of the Ministry of Transport conducted an accuracy test for AStep-1 LT and approved it as the second accuracy product in 1992

Evaluation Test conducted & Report Issued by,
Electronics Navigation Research Institute,
Ministry of Transport (MOT)
on November 1992
We achieved an improvement in accuracy with tests conducted on ships at sea, power saving, unlimited sea area for tests, and a reduction of time necessary for the test.
Outline of the product
AStep-1 LT conducts the measurements for speed and movement of ships utilizing a very high accuracy in surveying functions with DGPS. It also enables you to obtain data of such things as gyro and steering while measuring speed and sea routes. The software called "PostProcess" enables you to adjust current and create charts and reports.
