Proprietary information and specifications subject to change without notice.3.5 Jupiter binary data messagesThis section describes the binary data messagesof the Jupiter GPS receiver. All output and inputbinary messages are listed in Table 3-4 togetherwith their corresponding message IDs. Power-updefault messages are also identified.Binary messages are transmitted and receivedacross the host port serial I/O interface (RS-232),default communication parameters are: 9600 bps,no parity, 8 data bits, 1 stop bit3.5.1 Binary output message descriptionsThis section provides details for each of the outputbinary messages.3.5.1.1 Message 1000 (geodetic position statusoutput)This message outputs the receiver’s estimate ofposition, ground speed, course over ground, climbrate, and map datum. A solution status indicates ifthe solution is valid (based on the solution validitycriteria), the type of solution, and the number ofmeasurements used to compute the solution.The polar navigation flag is used to indicate thatthe solution estimate is too close to the North orSouth Pole to estimate longitude. When this flagis true, the longitude and true course outputs areinvalid and are not updated. Users operating nearthe poles should use the ‘ECEF position statusoutput’ message. (See Table 3-5.)Message ID: 1000Rate: variable; defaults to 1 HzMessage length: 55 wordsWord No. Name Type Units Range1-4 Message header5 Header checksum6-7 Set time (Note 1) UDI 10 ms ticks 0 to 4 294 967 2958 Sequence number (Note 2) I 0 to 32 7679 Satellite measurement sequence number (Note 3) I 0 to 32 767Navigation solution validity (10.0-10.15)10.0 Solution invalid—altitude used (Note 4) Bit 1 = true10.1 Solution invalid—no differential GPS (Note 4) Bit 1 = true10.2 Solution invalid—not enough satellites in track (Note 4) Bit 1 = true10.3 Solution invalid—exceeded max EHPE (Note 4) Bit 1 =true10.4 Solution invalid—exceeded max EVPE (Note 4) Bit 1 =true10.5 Solution invalid—no DR measurements (Note 5) Bit 1 = true10.6 Solution invalid—no DR calibration (Note 6) Bit 1 = true10.7 Solution invalid—no concurrent DR calibration by GPS (Note 7) Bit 1 = true10.8-10.15 ReservedNavigation solution type (11.0-11.15)11.0 Solution type - propagated solution (Note 8) Bit 1 = propagated11.1 Solution type - altitude used Bit 1 = altitude used11.2 Solution type -differential Bit 1 = differential11.3 Solution type - PM Bit 1 = RF off11.4 Solution type – GPS (Note 9) Bit 1 = true11.5 Solution type – concurrent GPS calibrated DR (Note 10) Bit 1 = true11.6 Solution type – stored calibration DR (Note 11) Bit 1 = true11.7-11.15 Reserved12 Number of measurements used in solution UI 0 to 12Table 3-5 (1 of 2) Message 1000 (geodetic position status output)
