Chris Wilson Posted July 31, 2008 Share Posted July 31, 2008 How much would I have to pay for a 20 Hz GPS unit with RS232 output? Before you ask me anything techie I don't know anything about GPS, save that I can connect such a thing to my Motec dash and it'll use it for logging without a track beacon. Cheers. I believe a firm called Blackline may make one? Quote Link to comment Share on other sites More sharing options...
bolarbag Posted July 31, 2008 Share Posted July 31, 2008 Couldnt you pickup a cheap pda with one in it, just bodge a serial connector onto it if the motec needs a serial cable I thought about doing this, I've seen it done I'm sure Quote Link to comment Share on other sites More sharing options...
Wez Posted July 31, 2008 Share Posted July 31, 2008 I been looking for this as well Chris, let me know if you find anything. Quote Link to comment Share on other sites More sharing options...
JustGav Posted July 31, 2008 Share Posted July 31, 2008 You will need to find out what sort of input the motec expects, GPS usually comes in a simple NMEA format, however some aren't always. If the motec takes NMEA then you are laughing, in fact I have got a serial based GPS unit somewhere at home you could have Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 31, 2008 Author Share Posted July 31, 2008 You've lost me already! I will have to ask my Motec man just what it needs. I know only that 10 Hz is OK, 20 Hz much better. Is that some sort of refresh speed? Thanks. Quote Link to comment Share on other sites More sharing options...

Is that some sort of refresh speed? Thanks. Yeah, I would assume that is the sampling speed. ie it gives GPS info 20 times a second (20hz)... I'll dig out the one I have at home, and if it is a go, just remind me and I'll post it up to you. Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted July 31, 2008 Share Posted July 31, 2008 Old serial GPS units aren't likely to be updating anywhere near 20Hz though are they? I seem to remember getting an update every 2 seconds on one a few years back, so 0.5Hz 10 or 20Hz may be quite specialised. Quote Link to comment Share on other sites More sharing options...
Wez Posted July 31, 2008 Share Posted July 31, 2008 20Hz GPS Data-Logger - Racelogic VBox VB20SL3 This new model VBox is a 20Hz GPS data-logger which can measure Speed, Pitch, Roll, and Yaw (Slip) angles. Key features include an advanced triple-antenna GPS engine with 20Hz update rate for highly accurate measurements of Speed (0.1km/h), Distance (0.05%), Acceleration (0.5%), simultaneous Slip, Pitch and Roll angle (Slip angle to 0.1° rms, Pitch and Roll angle to 0.25° rms), Yaw Rate (0.1°/s), True Heading (0.1°) and Lateral Velocity (0.1km/h). Justin Mellors, Sales Manager of Applied Measurement Australia commented “the key benefit of this exciting new product is that it represents a single, self contained, fully portable testing platform.” The unit also features a bright LED display screen, CAN bus, RS232 and USB interfaces, 2 x analogue I/O’s, 2 x digital I/O’s, data logging to SD card and is fully configurable via the front panel. A voltage input range of 6V – 30VDC, combined with the small, lightweight construction and simple installation procedure, means that the VB20SL3 is ideally suited for use in many applications including cars, bikes, off-road vehicles and especially boats.
