Is SiRF Binary Protocol a permanent configuration? ġ8.) Q:What can I do to prevent my device from having GRMC NMEA time stamp data problem? ġ8.) A: There is backed battery for SRAM and RTC (Real-Time Clock) to keep last stored position, date ,time, satellite data. Greater the cable length, less sensitivity quality. ġ6.) Q: What is the recommended maximum cable length for wired GPS devices? USB? Serial? ġ6.) A: We recommend 1.5m (4.92 ft.)/ 3m (9.84 ft.) cable length for USB/ Serial GPS device. If you are unsure about whether your vehicle has one of these types of windshields, contact your dealer and request more information. Customers with these types of windshields must use an exterior GPS antenna for improved results for GPS applications. ġ4.) Q: Why am I not getting any or very weak GPS signals even though my GPS receiver is directly under the windshield glass? ġ4.) A: Certain vehicles may be equipped with special windshields that contain metal in the glass that prevents GPS and RF signals from being received properly. What can I do to correct this? ġ3.) A: Under GPSInfo application select a ìCold Startî to reset receiverís registers.

Environment: highway, no high trees and buildings. Sometimes it took as long as 7-9 minutes (solid green LED). ġ3.) Q: Lately it takes too long to lock the satellites. Then the receiver will revert back to its original default settings. Note, custom settings are temporary until the receiver has exhausted both the internal Super-Cap. ġ2.) Q: Can I reconfigure receiver's NMEA data? If so, what program? ġ2.) A: Yes.

ġ1.) Q: Can I reconfigure receiver's Baud-Rate? If so, what program? ġ1.) A: Yes. ħ.) A: GGA(1sec), GSA(5sec), GSV(5sec), RMC(1sec) Ĩ.) Q: What is the output format for this receiver? Ĩ.) A: Output format: GGA(1sec), GSA(5sec), GSV(5sec), RMC(1sec),( VTG and GLL are optional) ĩ.) Q: How many satellites are needed for 3-D positioning? ġ0.) Q: Can I reconfigure receiver? If so, what program? ġ0.) A: Yes. ģ.) Q: How important is having WAAS enabled on your GPS receiver? ģ.) A: It provides better accuracy up to 3m Ĥ.) Q: What satellite identification number is used for WAAS and EGNOS? Ĥ.) A: Satellite #33 (AoRE) is for EGNOS, Satellite #35 (AoRW) is for WAAS, and it has been suggested that Satellite #41 (PoR) will be used to indicate that data is being received from the Japanese MSAS system. 1.) Q: What chipset is my BU-353-S4 using? Ģ.) A: Yes, the BU-353-S4 serial GPS receiver is WAAS enabled by default, it was sold by USGlobalSat, Inc and its Authorized Dealers.
