Time & Distance Reporting

The Antares 4G can automatically send position reports at regular time or distance intervals using the TD command.

How It Works​

Each TD slot (TD0–TD9) activates signal TDN when:

  • Time elapsed ≥ MIN_TIME since last report, AND
  • Distance traveled ≥ DISTANCE since last report,
  • But never more frequently than MIN_TIME seconds.

If MAX_TIME is set and the vehicle is stationary (distance not met), a report is still sent every MAX_TIME seconds.

Configuration​

>STD{N}{MIN_TIME}0000{DISTANCE}{MAX_TIME}<

All fields are zero-padded 4-digit integers:

FieldUnit
MIN_TIMESeconds
DISTANCEMeters *100
MAX_TIMESeconds

Example — report every 60s minimum, every 500m, max 5 minutes:

>STD00060000000050300<

Use in Events​

Create events that fire when TD signals activate:

>SED20NA0;TD0+<    ← Send report on TD0 trigger

Since TD0 fires and then resets (falling edge handled internally), you typically only need the rising edge (+).

Multiple Slots​

Use different slots for different purposes:

>STD00120000000000000<    ← TD1: every 2 min 
>STD10600000000103600<    ← TD2: every 10 min and 1 km or 60 min max
