The Holux 210 is our favorite GPS receiver for GPS2LT . It has a good set of
features, and is still one of the lowest cost receiver we’ve found. All of the electronics are in the housing that mounts on the roof. The attached cable goes
through the window and plugs into the USB connector on your laptop. It gets power from the USB connector so you only have one cable.
It has the required features we need for travel time studies; it mounts on the roof (it comes standard with a magnetic mount), it has a serial port to connect to the
laptop or PDA, and it outputs NMEA sentences at one second intervals. There also is a software utility to restrict the number of output sentences, which is
needed if you use this receiver with an older Palm PDA running GPS2PDA.
The Holux 210 is WAAS compatible, which is a nice feature even if we aren’t sure it is helpful for our particular application
.
You can find out more about the Holux 210 here. This is a review from a company in the UK but you’ll get the idea.
Here is one source to buy this GPS receiver. This is the version you want for GPS2LT. They buy the units from Holux and
put their own name on it, but it is the same receiver. The last time we checked, it was selling for $98, which includes the receiver and a cable to go to the USB port on your computer.
If you are looking for a GPS receiver for GPS2PDA, then this is still a good receiver for most situations. Make sure you
get the proper cables to work with your PDA. You need a cable that connects to your PDA and a cable to supply power
to the receiver, usually from the cigarette adapter in your car. Check the web site carefully to make sure you get the right combination of receiver and cables. Here is the model you want for a Palm PDA like the Palm m130 we like. If you need
with other PDAs then let us know and we can help you.
If you also use Jamar Trax counters and would like to use your PDA to retrieve and validate the data in the counters (click here for info on TraxPDA), then you might want to use a Pocket-PC based PDA with a GPS receiver that plugs into the
Compact Flash slot. This leaves the standard serial port available to connect to the Trax counter without requiring you to unplug cables or modules in the field.
