- To: ham-space@ucsd.edu
-
- My first AO-13 contact was with KC0TO/7 in Wyoming on 30 July at 0607 UTC.
-
- He gave the QSL route, but I misplaced it.
- My card to the callbook address for KC0TO was returned undeliverable.
-
- Does anyone have the correct QSL route?

- Does anyone know if the new Kantronics KPC-9612 dual speed TNC can be
- used to communicate with the 9600 baud satellites?

- Subject: New satellite Windows programs
- To: ham-space@ucsd.edu
-
- I just received my copy of the July/August 1994 issue of THE AMSAT JOURNAL.
- In the journal, pages 6-9, they talk about a new Windows PB and PG like
- program by ZL2TPO. The program also has a fully intergrated color graphic
- world map showing satallite positions and foot prints. It has full support
- for the Kansas City Tracker/Tuner, with the optional Windows program by
- KC6WYG, on page 10.
-
- Both programs can be purchased from AMSAT direct for $40.00 @ 301-589-6062
- All proceeds go to the Phase3D program.

- 73s, Tom WB7ASR...

- : You aren't going to be able to get a GPS and cell phone for a couple
- : hundred dollars. The cheapest GPS receivers are around $400, and so
- : are cell phones unless you roll their cost into a long term service
- : contract. And monthly and per minute cell phone charges will mount
- : up fairly rapidly. By using packet radio, amateur or commercial,
- : you can send position updates on a regular basis without incurring
- : quite as much cost.
-
- : DeLorme Mapping and City Streets are a couple of commercial map
- : systems that work with GPS. However, APRS (Automatic Packet Reporting
- : System) is in some ways better. While it lacks the friendly user
- : interface of the commercial products, and it's pre-made map databases
- : are skimpy, you can make your own maps, and it works with local and
- : remote GPS receivers (using packet UI frames for the latter). It also
- : supports other information about the remote sites such as range and
- : bearing data from DF equipment, and arbitary text messages.
-
- : However, what many of us want is *differential* GPS. The Coast Guard,
- : FAA, and others send out position deltas from a fixed benchmark
- : receiver that are received and used to correct the reading of the local
- : GPS receiver. These transmissions are either at MF or VHF depending on
- : the system. A special receiver is required, and either a GPS receiver
- : designed to work with differential signals, or a PC that can take the
- : timestamped position reports and reconcile them via software, is used
- : to give a true position. This method removes the deliberate SA jitter,
- : and other error sources such as varying atmospheric propagation factors,
- : from the position data. This allows much greater precision in determining
- : location than raw GPS alone.
-
- : It would be nice if the APRS author would support this mode in his
- : software. Some of us are willing to set up benchmark receivers on
- : the amateur bands. That timestamped data could be used to correct
- : the positions reported by the rover receivers over packet.

- This has already been done on an experimental basis here in the Annaoplis
- area: A cooperating ham otransmits a differential signal on the same
- freq as the APRS net. Receive it thru your TNC and it goes into the
- GPS receiver. Works fine.
