1
Capture a Skypatrol fingerprint
Confirm a UDP datagram with API 5, type 2, message 1, and an 8- or 22-byte ASCII unit id.

Point Skypatrol at 5021
Configure only Skypatrol to UDP 5021. Skypatrol on 5021 is not Smokey on 5125 or Snapper on 5256.
-
3
Do not wait for an ACK
Skypatrol has no reply byte. A parsed status-1 report is enough.
-
4
Prove one Skypatrol fix
Send one API 5 report whose GPS status byte is 1 on 5021 and verify a map point.
Still offline after GPS lock
Skypatrol still not landing
- Skypatrol aimed at the wrong port
Skypatrol on 5021 is not Smokey on 5125 or Snapper on 5256.
- Skypatrol session up, empty map
GPS status must be 1. Any other status byte binds the id and will not plot.
- No ACK, assumed dead
This dialect has no reply byte. Check the map, not the socket for an ACK.
FAQ
Skypatrol leftover questions
Does Skypatrol send Concox 0x7878 frames?
No. Skypatrol is a binary API 5 report with a mask and an ASCII unit id of 8 or 22 bytes. Concox families use 0x7878 binary login.
Which GPS status byte plots a Skypatrol fix?
1 plots. Any other status byte can still bind the unit id and will not plot.
How does Skypatrol pack latitude and longitude?
Each axis is an unsigned int as degrees plus minutes/60. A packed value above 0x7fffffff is the opposite hemisphere (subtract from 0xffffffff and flip the sign).
How long is the Skypatrol unit id?
8 ASCII bytes when mask bit 23 is set. 22 ASCII bytes when mask bit 2 is set. Neither bit means the datagram will not bind.
Can a Skypatrol unit run SMS setup or a controlled-action flow?
This dialect is positions only. Catalogue devices include TT8750+, TT9500, and SP1824. There is no SMS family on this row.
