Affordable 10Hz GPS?

David Lundin

I've seen a couple of threads, one is quite old and the other one is in finnish of which I don't understand a word.

Are there any affordable real 10Hz GPS units around today (which should work well with RaceChrono), or are we still limited to BlackLine and similar which are very pricey?

For my knowledge there are still no affordable Bluetooth GPS receivers that would do real 10 Hz (real meaning not interpolated). Recently I was contacted by one manufacturer who planned to do one, so there is some hope to have one.

Sounds promising at least, keep us posted :-)

Btw, I decided 20 Euros was something I could definitely part with for such a nice product as Race Chrono (especially with such great support). Unfortunately PayPal is taking ages to confirm my identity so I can't do anything at all yet... annoying.

What about this gps unit? http://www.skytraq.com.tw/download/Venus_CeBIT5.pdf
It's cheap enough, but you have to pair it with a BT transmistter to make it work with a phone. I cant tell if it's true 10Hz or interpolated...

Opt123: Can you point me to a GPS receiver that has this chipset?

is not very serious at first sight ... this seems interpolated, but not very clear!

Yep, that test does not look too promising. I'd like to see some more tests with the newer firmware.

About SkyTraq and Venus6 chipset. I got a reply by mail from a French retailer, is interpolated 10Hz!

I ordered a QStarz BT-Q818XT which claims to have 10Hz refresh rate. The retail price from the shop I ordered it was 149 euros. Hope this helps.
