The only reason I did not save speed or heading was because all I wanted was position information. The plan was to create a GPS data logger that would record the position of the unit and allow me to read back the latitude and longitude after acquiring the data. I woudl want them so I could Geotag my photos. Please check your email to confirm. It has been sitting in the back of my car for the past four years, so I finally decided to put it to good use. The following was executed on my unit and tested, but, as always, you MUST accept responsibility for any damage to your computer, Tripmate or any think else resulting from using and executing the following information.

DeLorme Tripmate GPS Receiver

It turns on the sentence with whatever time interval was previously set. Please only respond to my questions if you are so incline.

Get the Magazine Make: This is for a delrme club transmitter hunting competition where competitors have to Direction Find DF the transmitter in the shortest time and distance. If you know the source, please email me so that I can post the credit or switch to a valid link.

Place the connectors back to back and solder the wire connectors for pins skip pin 5 together.

Your method seems like a much easier approach. Right now it is configured in such a manner that it will only log the GPRMC sentence, but it can easily be modified. A few years ago found a Qbasic routine that at least gets me back the ability to retrieve coordinates from the expletive deleted thing.


Very cool project…Thinking of making robotic submarine with some sort of gps built in. If you haunt electronic supply houses, find one of these connectors with pins designed to fit into a pc board rather than wire cups on the back and they will fit together perfectly to join with solder. Education How making is transforming learning.

Running a hot glue gun all of the way around the join of the two connectors is then the best way to insulate the soldered connections, but it is important that they be insulated. My ultimate goal will be to use a small backpack to record my runs once the weather warms up. This allows for quick and easy debugging.

It has a rewrite endurance of 1, cycles and can operate between 2.

More information about the self-start modification can be found on these websites:. Leave a Reply Cancel reply.

This is the default for this sentence. This was a fun experiment because not only did I need to interface the PIC16F88 to the Tripmate, but I also needed to parse the output and implement an teipmate storage solution. Even a kit of parts? Read on to find out more information about the project, see the schematic and soure code I wrote, and find out how the data was visualized.

I modified my Tripmate to self-start deoorme a loopback modification. Find Your Longitude and Latitude here. We all get timing slips, as we motor down the salt, at one mile increments but this would be great data to have in between the mile markers.

I will discuss each of the components below.


I happen to have one that my family used a couple of years ago and it is still in great shape. It has been sitting in the back of my car for the past four years, so I finally decided to put it to good use. If you or anyone else reading this wants to track my progress, I will be posing it online hopefully soon.

PIC16F88 Delorme Tripmate GPS Logger

Seeing as I don’t know what information this sentence provides, it seems like a tripmaye thing to send to reduce the amount of tripmage sent.

I happen to have one that my family used a couple of years ago and it is still in great shape. The job of the microchip will now be to parse this data, discard any irrelevant information, and store the variables of interest Latitude and Longitude. Power Supply This is the only component that is ambiguous in the schematic.

Since the Tripmate itself puts out the “ASTRAL” string repeatedly when it is inactive, another solution has been to rewire the serial connector so that this string is routed back to the receiver to wake it up. Please check your email. Modify the Delorme Tripmate to selfstart Delorem Self-Start and External Power Mod Once the Tripmate is modified to self-start, it will automatically output position and satellite information when power is applied.
