2018-03 Compact Air Temperature (CAT4)

  The newly developed CAT4 integrates the HF antenna, flashlight and an air temperature sensor. The air temperature sensor applies a novel concept, which corrects the measured temperature for (solar) radiation and detects evaporation effects. The CAT4 antenna is in its final stages of development and will be available on most Waverider buoys (with the exception of the DWR-G4). First CAT4 instruments will be deployed by a set of selected customers to acquire first hand user experience.  



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.
