Table 13: Indicative power requirements
Values in Table 13 are provided for customer information only as an example of typical power
requirements. Values are characterized on samples, actual power requirements can vary depending on
FW version used, external circuitry, number of SVs tracked, signal strength, type of start as well as time,
duration and conditions of test.
11
Use this figure to dimension maximum current capability of power supply. Measurement of this parameter with 1 Hz bandwidth.
12
Use this figure to determine required battery capacity.
13
>8 SVs in view, CNo >40 dBHz, current average of 30 sec after cold start.
14
with strong signals (>130 dBm), all visible satellites are tracked (>7 SV). For Cold Starts typical 12 min after First Fix. For Hot Starts typical
15 sec after First Fix.
