Signal generator of imitate of satellite of IFR GPS-101 GPS
The system of global satellite location that desired result place lades (GPS) the job

Receiver of GPS of fast desired result operates integrtes integrality
Optional satellite lades implement (SV) with navigation (NAV) data
RF n is adjustable limits is in - 85dBm comes - inside 145dBm, adjust with 1dB interval
Much general straps frequency to move control can make handlers chooses about the carrier wave frequency of ±4kHz moves

Simulator of system of location of IFR GPS-101 whole world locates to the whole world system (GPS) offer mix accurately successive test. Satellite of fixed position of a whole world produces GPS-101 imitate carrier of a specific satellite (SV) will complete this test with navigation data model. Along with is record in information of GPS single-page calendar and RF n remotely / frequency control, GPS-101 offers a portable test solution to system of GPS of test and verify.

GPS-101 but desired result is the following the equipment of the type:
A complete GPS receiver —— takes aerial system (for instance one holds package) , buy checks mode inside, lade through receiving specific satellite implement (SV) number and navigation data word can arise show, may receive information in order to receive and show.
The airborne GPS receiver of aerial system is received outside the belt.
Any GPS receiver or device, have the ability that shows single satellite and place explore navigation data.
The special key on the face plate before operating GPS-101 is used at the choice of all main functions. The parameter of the choice shows in wide perspective, tall contrast, have powerful connections the liquid crystal of the lamp shows screen to go up.

Mode key
RFLVL: Radio frequency n can be adjusted by knob, limits - 85dBm arrives - 145dBm, step is 1dB, have with desired result GPS.
DPLR: The receiver of test and verify of immigrate of carrier wave frequency that much general straps control to be able to make handlers choice is ±4kHz about is explored and lock up calm function.
SV: Choose satellite of imitate 1-37 date. If abnormal or the satellite is invalid, the satellitic name that choosing counts data of the single-page calendar on the edge to show * sign.
RF CONT: RF control chooses modulation source for 1575.42MHz signal generator. Choose RF OFF, carrier wave is shut; Choose RF CW, for C/A code and NAV data (enlarge frequency signal) ; RF EXT, pass AUXI/O join for exterior BPSK modulation; RF SQR, for modulation of 511.5kHz square wave (safeguard with) .
SET UP: Parameter of port of set RS-232/422 communication, setting checks character and self check.
TEST: A of the NAV data model that chooses 3 memory. (withhold 3 data model to be used in order to offer in the future additionally)
T1: NAV data includes but information of process designing single-page calendar and GPS Zhou Shu and time. Single-page calendar data inside 30 days of cycle effective, can pile up text format download with "YUMA" ASCII by RS-232 port. Data of active single-page calendar from U.S. Coastal guard website gets. GPS-101 has time of UTC of the Zhong Baocun when an in-house real time, but by process designing of the person that use.
T2: NAV data model includes fixed GPS Zhou Shu and time.
T3: 11001100 fixed. . . Retest signal.
Choose key: Mobile cursor chooses a field / parameter.
Indication key: Contrast setting key is in a poor light with indication screen the lamp leaves / crucial.
ESC key: Return advocate operation screen.
Knob: Can choose data quickly.
