14.2. SENSITIVITY

14.2.1. TRACKING

Tracking is an ability of receiver to maintain valid satellite ephemeris data.

During tracking receiver may stop output valid position solutions.

Tracking sensitivity defined as minimum GPS signal power required for tracking.

14.2.2. REACQUISITION

Reacquisition follows temporary blocking of GPS signals.

Reacquisition sensitivity defined as minimum GPS signal power required for reacquisition.

14.2.3. NAVIGATION

During navigation receiver consequently outputs valid position solutions.

Navigation sensitivity defined as minimum GPS signal power required for reliable navigation.

14.2.4. HOT START

Hot Start sensitivity defined as minimum GPS signal power required for valid position solution

under Hot Start conditions.

14.2.5. AIDED START

Aided Start sensitivity defined as minimum GPS signal power required for valid position solution

following aiding process.

14.2.6. COLD START

Cold Start sensitivity defined as minimum GPS signal power required for valid position solution

under Cold Start conditions, sometimes referred as ephemeris decode threshold.

TABLE 6 – SENSITIVITY

Notes:

1. EVK is static, ambient temperature is +25°C, RF signals are conducted.

2. R01 - Dual-stage LNA standard ordering option.

3. Outage duration ≤ 30s.

4. Hibernate state duration ≤ 5m.

5. Aiding using Broadcast Ephemeris (Ephemeris Push™) or Extended Ephemeris (CGEE™ or SGEE™).
