AB Utilizing broadband low Earth orbit satellite signals in an opportunistic manner for navigation is becoming increasingly popular. This paper deals with a particularly useful approach for navigation based on satellite signals of opportunity, which uses carrier Doppler-shift observables. We provide analytically derived and simplified formulas for the Jacobian involved in the numerical computation of the navigation solution and derive a global navigation satellite system-like dilution-of-precision metric that can be used to assess accuracy. A numerical study provides preliminary computational results.ADRaccumulated delta rangeAOAangle of arrivalCBDOPclock bias dilution of precisionCBRDOPclock bias rate dilution of precisionDOPdilution of precisionECEFEarth-centered Earth-fixedGDOPgeometric dilution of precisionGNSSglobal navigation satellite systemGPSGlobal Positioning SystemHDOPhorizontal position dilution of precisionINSinertial navigation systemLEOlow Earth orbitLOSline of sightMEOmedium Earth orbitmpsmeters-per-secondNEDnorth–east–downPDOPposition dilution of precisionPBFPsiaki batch filterPNTpositioning, navigation, and timingRREDSrange-rate equivalent Doppler shiftSoOpsignal of opportunitySTANsimultaneous tracking and navigationTDOAtime difference of arrivalTLEtwo-line elementTOAtime of arrivalVDOPvelocity dilution of precision
