Proprietary information and specifications subject to change without notice.3.10 Dynamic constraintsThe Jupiter 20 receiver is programmed to deliberately lose track if any of the following limits areexceeded:Velocity: 500 m/s maxAcceleration: 4 G (39.2 m/s2) maxVehicle jerk: 5 m/s3 maxAltitude: 18 000 m max (referenced to MSL)3.11 Position and velocity accuracyThe position and velocity accuracy of the Jupiter 20 are shown in Table 3‑4, assuming fullaccuracy C/A code (Clear/Acquisition). These values are the same in normal operation andwhen TricklePower is active.Parameter J20/J20D J20Shorizontal CEP 2.1 m 2.2 mhorizontal (2 dRMS) 5.2 m 5.5 mvertical VEP 2.5 m 2.5 mvelocity 2D (2 sigma)* 0.1 m/s 0.15 m/s*at a velocity greater than km/hTable 3-4: Position and velocity accuracy4.0 Electrical requirements4.1 Power supply4.1.1 Primary powerThe Jupiter 20 GPS receiver is designed to operate from a single supply voltage, meeting therequirements shown in Table 4‑1.Parameter J20 J20S J20Dinput voltage 2.9 to 3.6 VDC 2.9 to 3.6 VDC 2.9 to 3.6 VDCcurrent (typ) at full power (3.3 V) 75 mA 85 mA 80 mAcurrent (max) 100 mA 100 mA 100 mAcurrent (typ) at 20% TricklePowerTM 35 mA 60 mA 35 mAbattery backup voltage 2.4 V to 3.6 Vbattery backup current <10 μA typ at 25°Cmaximum rise time unlimitedripple not to exceed 50 mV peak to peakTable 4-1: Operating power for the Jupiter 204.1.2 Low supply voltage detectorThe module will enter a reset mode if the main supply drops below 2.8 V.4.1.3 VCC_RF power supplyThe VCC_RF (pad 20) provides a regulated 2.8 V power source. The specifications for thissupply are as follows:voltage: 2.8 V ± 2%current max: 25 mA for J20/J20S; 5 mA for J20D
