APPENDIX B - OUTPUT PROTOCOLS
The available output data formats are as follows:
Name Format no. Description
PSXRAD 1 NMEA proprietary messages
Fanbeam BCD telegram 2 Fanbeam binary format
ARTEMIS 3 Pseudo Artemis, ASCII 17 bytes format
ABB DP 4 Pseudo Fanbeam, ASCII 333 bytes adapted for ABB DP.
5.1 PSXRAD, NMEA proprietary format
The NMEA format is an ASCII text format based on the NMEA 0183 standard defined in [1].
RADius utilises the proprietary PSXRAD format described below.
Format:
Note that this telegram is repeated for every Transponder tracked. The field marked ss is a
sequence number indicating what telegram this is of a total of the number of transponders
initiated for tracking (indicated by field nn).

I
ID for Interrogator, range 0-9
hhmmss.ss
Time of position hour, minutes, seconds
nn
Number of transponders set up for tracking, range 0 – 99
ss
Sequence number (multiple transponders), range 0 – (nn-1)
tid
Transponder ID, the number is the transponder frequency in 10KHz resolution.
150 is then 1.5 MHz transponder
rrrr.rr
Range in meters, decimal centimetres
aa.a
Range accuracy estimate (1 σ level in m)
bbb.bb
Bearing to transponder 0.00 to 360.00 degrees
ss.s
Bearing accuracy estimate (1 σ level in deg)
±vv.vv
Vertical angle to transponder (-90.0 - +90.0), the + sign is omitted when
positive.
ff.f
Vertical angle accuracy estimate (1 σ level in deg)
±dd.dd
Velocity relative to transponder (doppler) m/s, the + sign is omitted when
positive.
sn
Signal to noise in DB 0 – 90, less than10 is not good, 10 – 15 is week, > 15 is
good
S
Status 0 – 9 (0 – No reply (not tracking transponder), 1 – Other error, do not
use, 2 – Range only, 3 – 8 TBD, 9 – Valid Status)
*cc
Computed checksum
