4.1.1 Primary power
The Jupiter 31 GPS receiver is designed to operate from a single supply voltage, meeting the
requirements shown in Table 4-1.
4.1.2 Battery backup (SRAM/RTC backup)
During ‘powered down’ conditions, the SRAM and RTC (Real Time Clock) may be kept
operating by supplying power from the VBATT as shown in Table 5-2.
4.1.3 Low supply voltage detector
The module will enter a reset mode if the main supply drops below 3.0 V.
4.1.4 RF (Radio Frequency) input
RF input is 1575.42 MHz (L1 Band) at a level between –135 dBm and –159 dBm into a 50 Ω
impedance. This input may have a DC voltage impressed upon it to supply power to an active
antenna. The maximum input return loss is –9 dB.
4.1.5 Antenna gain
The receiver will operate with a passive antenna with unity gain. However, GPS performance
will be optimum when an active antenna is used. The gain of an active antenna at the input of
the module is ideally 16 dB.
4.1.6 Burnout protection
The receiver accepts without risk of damage a signal of +10 dBm from 0 to 2 GHz carrier
frequency, except in band 1560 to 1590 MHz where the maximum level is –10 dBm.
4.1.7 Jamming performance
The jamming performance of the receiver based upon a 3 dB degradation in C/N
performance is shown in Table 4-2. This is with reference to the external antenna. These
results are determined using a CW (Continuous Wave) Jammer.
