Pro Track data format - leg0/paralog-tools GitHub Wiki
Header
The first line contains constant string "DATA TRACK VER. 1.05". Second line is "3FC0" which is the number of hex-encoded bytes that will follow (i.e. 16320). Each line that follows contains exactly 200 hexadecimal digits, except the last one which is 40 digits. So, (200 chars/line * 163 lines + 40 chars) / 2 chars/byte = 16320 bytes, this confirms that the second line is indeed the size.
Data
In the following table the offsets and lengths are in units of 2 hexadecimal digits, or bytes after converting the data to binary.
| offset | length | description |
|---|---|---|
| 10 | 1 | First digit of serial number |
| 11 | 2 | ? |
| 13 | 6 | Serial number. The example data contains 03 0C 0D 21 27 4B, which Paralog interprets as 3-312-13-33-39-75-202. Where the first 3 and 202 in the end come from is unknown. 03 0C => 312, 0D => 13, 21 => 33, 27 => 39, 4B => 75 |
| 300 | 200*30 | Short records of last 200 jumps. |
| 6300 | 10*1000 | Long records of last 10 jumps. |
| 16300 | 20 | Looks like bunch of 0xFF. Probably nothing interesting. |
Short record

| offset | length | example | description |
|---|---|---|---|
| 0 | 2 | 04B3 | Jump number. 0xFF is not used in jump number values. jump number 255 is not 0x00ff, but is instead 0x1000 |
| 2 | 2 | 3068 | Exit altitude in feet. |
| 4 | 2 | 1152 | Opening altitude in feet. |
| 7 | 2 | 31 | Delay in seconds. |
| 8 | 1 | 0A | Jump type 0 = ?, 1=Profile1, 2=Profile2, 3=AFF, 4=Tan, 5=Stu, 6=Pho, 7=4way, 8=8way, 9=free, 10=slo, 11=spc |
| 9 | 1 | 06 | Day |
| 10 | 1 | 06 | Month |
| 11 | 2 | 07E5 | ? |
| 13 | 2 | 0075 | Average speed in mph. |
| 15 | 2 | 008F | Maximum speed in mph. |

Long record
| offset | length | example | description |
|---|---|---|---|
| 0 | 2 | 04D5 | Jump number |
| 2 | 2 | 03EB | Presure at sea level in kPa |
| 4 | 2 | FFFF | ? |
| 6 | 2 | 0383 | Temperature at sea level in 0.1F? |
| 8 | 2 | FFFF | ? |
| 10 | 494*2 | ... | A list of 494 pressure measurements. Pressure in kPa. Measurement frequency 4Hz. |
| 998 | 2 | 03E9 | Number of bytes in the record. |
Decimal value about 6000 in the pressure measurements list seems to correspond to about 4km and value 9000 to about 1km. Based on the results with this calculator, my guess is that the unit of the values is 10Pa. The interval is still unclear.
