What triggers the sleep mode, and how long does it take for the Loko GPS tracker to enter sleep mode after transmitting the position information (POS).

LOKO Sleep Interval and GPS Update Process.
The LOKO sleep interval is user-defined and can be configured via the settings. During the specified sleep interval, LOKO enters a low-power sleep mode. At the end of the interval, it wakes up, powers on the GPS module, and begins searching for a new GPS fix. Once a new GPS position is acquired, LOKO turns off the GPS to conserve energy, transmits the new location data to the Ground Unit, and returns to sleep mode.
Under open sky conditions, acquiring a new GPS fix and completing the transmission typically takes 8–10 seconds. However, in environments with weak GPS signals (e.g., due to buildings, trees, or weather), acquiring a fix may take longer. If LOKO cannot obtain a new GPS fix within 60 seconds, it will transmit the previously recorded location and return to sleep mode.

When the user powers on LOKO for the first time, acquiring the initial GPS fix may take longer than usual. This is due to a cold start, especially if the device is in a new or distant geographic location compared to its last known position. During a cold start, the GPS module must download satellite data from scratch, which can significantly increase the time required to obtain an accurate location fix.
