Unless your exact location between point A and B is important, simply enter your estimated average speed, and the straight line course to B.This way, other stations will be able to see your dead-reckoned progress toward B and you will not have to make frequent updates. The APRS MIC-Encoder will revolutionize mobile radio! OVERVIEW: Although APRS on boats and aircraft already equiped with GPS or LORAN is obvious, it is IMPORTANT TO NOTE THAT APRS IS STILL VERY USEFUL FOR VEHICLES WITHOUT GPS TOO!It plugs into the Mic jack of any radio and puts your APRS-GPS posit on the tail end of any VOICE transmission. Actually, the only stations that need GPS are the ones that are lost!Since APRS also DR's your progress on your own screen, you will see the same thing that everyone else sees.

This command also switches the APRS port-splitter circuit in HSP mode so that you could monitor the GPS.It only has dual flopies, but a minimum APRS system PLUS DOS will fit on a single 720K floppy.TO give you some more maps, though, you might want to use the DOS APPEND command to tell DOS to use the B drive as an extension of your A drive.MANUAL POSITION UPDATING: If a station knows where he is, he just zooms into his APRS map and moves the cursor to his location.Then he hits the INPUT-MY-POS command and enters his new course and speed.For this reason, the first section of this file will discuss the use of APRS in a vehicle without GPS.Note: Be sure to replay the DIGI-E, DIGI-W, or file before going on a trip so you can see where the digiepaters are...One station moving cross country reporting via HF set his course to 270 degrees and set in an average speed of about 50 MPH.Although he only updated his exact position once every few hours, because of the automatic APRS dead reckoning, his van appeared to everyone to move west giving a good approximation of his progress.There are several methods of interfacing depending on whether you have a dual or single port laptop, and whether your GPS/LORAN has a periodicity that is user programmable.Some useful commands are: Synchronizes your PC clock to the GPS time in the next GPS posit heard.
