sensitivity for weak signals without sacrificing accuracy, AGPS function, DGPS
function which is supported by RTCM, WAAS, and EGNOS, and flexibility for
system integrations. Because of 8192 frequency search bins at the same time, it
accelerates the start-up times of the module.
In addition to the above excellent advantages, FV-25 has the capabilities to perform
low power consumption due to the advanced hardware components and implement
power saving function owing to versatile firmware. The properties are very suitable
for battery-operated products. In addition, our module has the size of only 25.4 mm x
25.4 mm. This feature allows the module more executable and achievable in the
system integration, especially for the size-mattered products like handheld devices.
Because of using advance technology in package, the module is highly integratable
with other components and can be automatically assembled and proceeded in a
standard pick-and-place equipment and reflow soldering in high volume. Therefore,
the cost of module can be reduced.
1.1 Supports
For FV-25, we will provide a evaluation kit as an optional. The evaluation kit helps
the users to perform the estimation of the module, which includes the start-up times,
reacquisition time, setting of NMEA sentences, baud rate setting, etc.. All those
functions and evaluations are supported by
Sanav_Demo
, which accompanies with the
kit and is developed by San Jose Navigation, Inc.. Of course, for the customers
without purchasing the kit, a reference layout for peripheral connections and
Sanav_Demo
are available. The details of the reference layout and
Sanav_Demo
will
be described in Chapter 2. For the evaluation kit, its introduction is depicted in
Chapter 5.
The other available tool for evaluate the module is Window’s “HyperTerminal”. For
utilizing this tool and, at the same time, understanding the capability of the module,
the commands and messages for polling data or setting configuration are described in
Chapters 4 and 7.
