Since the introduction of GPS-Speedsurfing.com we have used several approved GPS-Devices, in recent years we switched over to Doppler supported devices, first introduced with the GT-11 and later the GT-31. Sadly the production of the GT-31 has reached the “End of Life” status, so the availability will be very limited in the next months.
Our Technology team has been working on other GPS-Devices in the last months, and we have been working on several parallel tracks. The first track is focused on the development of a new High-End GPS Devices, capable to measure with Doppler GPS functionality. This High-End Device will is based on the ThingSee, and is equipped with our own custom software, making it fully equipped for our special features like the 10 seconds run, the Nautical Mile, Alpha speeds, etc etc.
It's available for pre-sale rigjht now on http://shop.gps-speedsurfing.com/p/67/thingsee-one-gp3s-edition-v1
The second track that we working on is the use of other GPS Devices, most import device that will be on the market will be the Locosystech GX-52. This device already has been approved and we are very happy that Locosystech again produces a custom products with special GPS-Speedsurfing.com firmware on it out of the box. You can buy the device at several online & offline stores.
Besides that we have worked on standard devices, we realize that this standard devices will never reach the high-end specifications of Doppler GPS, but for normal day-to-day use, and the average surf-sessions this devices could be a nice alternative for some windsurfers. We are exploring the possibilities of enhancing the software of “standard” GPS-Devices. Target is to reach the current standards of GPS logging at GPS-Speedsurfing.com, so making it possible to measure at a 1 per second rate, and log the number of satellites.
In general we allow any GPS Devices that’s is capable of logging GPS Data with a sample rate of 1 per second and support the .GPX data format. Please notice that the use of .GPX format is not allowed for records, and is more suited for normal day-to-day surf sessions. The only fully approved format at this stage are the .SBN, .SBP & .UBX format.
For speedfreaks that already own a Android phone a good alternative good be the App GPS Logit, http://www.gps-speed.com/gpslogit.html , this App is still under development by Manfred Fuchs, and could be a good alternative for starting speedsurfers. The App produces doppler speeds, at the same quality level of the old GT-11 .
