2018-03 Introduction of GPS light detection for all buoys

by Beheerder on 26 March 2018 16:54

We have decided to introduce the GPS light detection system for all our Waverider buoys (except for the DWR-G4) where it was previously only available for the DWR4. A sunrise/sunset-algorithm based on the GPS position and time decides whether the LED flasher should be ON or OFF.

 

Should you desire to have this GPS light detection system installed on your current hatchcover (serial numbers starting with 70xxx, 71xxx and 72xxx), this unit will have to be returned to Datawell service department.

 

Hatchcovers produced after October 1st 2017 have the GPS light detection system already installed. We again stress that no change in the design of the antenna is made, which means that antennas are completely interchangeable.

Many Waveriders we supplied have been equipped with a Superstar GPS receiver. Recently it has come to our attention that the Superstar generates a faulty date in the logger files. The problem can be explained by an unexpected “GPS week rollover”. The internal date obtained from the GPS satellite system is incorrect. Typically the date is set to the year 2096. To convert the incorrect data we are currently developing a software tool. The only solution to this problem however is to replace the Superstar GPS receiver. The Superstar position module must be replaced with the µBlox GPS receiver (DWR-MKIII and WR-SG). The µBlox GPS receiver was introduced in the beginning of 2012.
