2.) Q: Is this device WAAS enable?
2.) A: Yes, it is WAAS enabled by default if purchased through USGlobalSat and it's Authorized Resellers.

3.) A: WGS 84
4.) Q: Is this device waterproof?
4.) A: Yes, IPX7

5.) A: GGA(1sec), GSA(5sec), GSV(5sec), RMC(1sec),VTG(1sec)
6.) Q: How many satellites are needed for 3-D positioning?
6.) A: A minimum of 4 satellites.
7.) Q: Can I reconfigure receiver? If so, what program?
7.) A: Yes. SirfDemo programming utility.
8.) Q: Can I reconfigure receiver? If so, what program?
8.) A: Yes. SirfDemo programming utility.
9.) Q: Yes. SirfDemo programming utility.
9.) A: Can I reconfigure receiver's Baud-Rate? If so, what program?
10.) Q: Can I reconfigure receiver's NMEA data? If so, what program?
10.) A: Yes. SirfDemo programming utility.
11.) Q: Can I reconfigure receiver for WAAS? If so, what program?
11.) A: Yes. SirfDemo programming utility.
12.) Q: What platforms are supported?
12.) A: Windows/ WinCE/ Mac OS X/ Linux
13.) Q: Is the device WAAS enable by default?
13.) A: Yes, it is WAAS enabled by default if purchased through USGlobalSat and it's Authorized Resellers.
14.) Q: Once set. Is SiRF Binary Protocol a permanent configuration?
14.) A: These settings are temporary until the receiverís internal Super-Cap back-up power supply. Then the receiver will revert back to its original default settings.
15.) Q: Does the current USB driver support Mac OS X Snow Leopard?
15.) A: Yes.
16.) Q: Will my receiver support older NMEA standards?
16.) A: Yes, NMEA 2.0 is backwards compatible with older versions of the protocol. NOTE: If your map software (such as Street Atlas 5) requires data sentence GGA, and your GPS (such as the Magellan 3000) does not output GGA, then they will NOT work together.
17.) Q: What to look for first to know which SiRF firmware version is oldest/newest?
17.) A: Here's a little insight into SiRF version numbers: 2.3.2-GSW2-2.05.024-C1PROD1.0_6A -- the GSW2 means standard SiRFStar II software, and 2.3.2 is the release version number. The 2.05.024 or similar numbers are internal numbers into the engineering data base. C1 is the build variant, a number that varies with each software type, but can relate to flash builds vs. RAM (debug) builds, builds with or without SBAS support (WAAS), builds with one or two serial port support, NMEA or binary protocol default, etc. Prod means this is a released rather than a beta (test) version. 1.00 means the release is without any post-release bug fixes. If there is a letter or letters after the Prod1.00, like Prod1.02b, this would mean that some specific "patches" have been added to provide interim fixes for known bugs. After that, anything on the line is likely added by the manufacturer for internal version control. A number like 2.4.12.07-XMitac2.0-C1BETA1.1 0000003729 with XMitac2.0 means this is XTrac 2.0 customized by SiRF for Mitac. In general, an X in the number will imply XTrac software, while GSW2 or GSW3 will indicate standard code for SiRFStar II or SiRFStar III, respectively.
18.) Q: Can we upgrade our SiRF firmware? What' s needed for the process?
18.) A: SiRF provides the new versions to our direct customers, but it is up to them to determine if they want to provide an update mechanism to their end-user customers. While the process is relatively simple, unless there is a hardware way to put the receiver into flash upgrade mode (internal boot mode is our term) there is a chance to get things stuck so you have to send it back to the manufacturer or a repair depot to recover. Further, you must be supplied with a flash programming utility to do the job since you cannot access the flash directly -- you have to go through the ARM processor on the SiRF chipset.
19.) Q: What is the meaning of "baud rate"?
19.) A: Baud rate is really the rate of bit transitions on the serial data link. Since each byte of data adds a start and stop bit, it is 10 bits long, and 38400 baud is 3840 bytes per second. Faster bit rates transfer more bytes per second, i.e., greater bandwidth.
20.) Q: What is trickle mode?
20.) A: Static navigation when enable, velocities lower than 1.2 m/s for 3 seconds we will freeze the position, and leave them frozen until velocity exceeds 1.4 m/s. Static navigation is a mode designed for motor vehicles, which causes the position to become pinned at one location when velocity is determined to be low enough. This is designed to make navigation systems operate more reasonably when the GPS Selective Availability (SA) signal degradation is turned on.
