9.0 Overview
The core engine of PCM-3292 is CT5510.
The data logging capability of CT5510 enables the storage of time and location
information in the built-in flash memory, while the module is navigating.
When logging, the receiver periodically stores new “log points”, which consist of
the current navigation information. There may be several different logs in the
module’s memory at the same time, so that different routes can be stored. The user
may upload the logged data from the module to a PC or other host devices for
observation and processing.
Users may choose how much information is stored along each point, affecting the
number of log points stored in the available memory. Each log point may contain
the following navigation information or a subset of them:
!
Llongitude coordinates with a resolution of 0.0000001 degrees (about
1 cm on earth surface).
!
Altitude with a resolution of 1 meter.
!
Time with a resolution of 1 second.
!
Horizontal and vertical velocity with a resolution of 0.01 m/s, direction of
movement with a resolution of 0.01 degrees.
!
Fix quality information like the number of satellites used in a fix, 2D/3D fix
indication, HDOP value with a resolution of 0.1 units.
User may also set various conditions for how often new data points are added to
the log:
!
Minimum and maximum time may elapse between logging points.
!
Minimum and maximum distance the receiver may move between logging
points.
Depending on the logging settings, between 14000 to 39000 log points can fit into
the memory of a standard CT5510 module with 8Mbits of flash memory.
The logging capability is not available in CT5510 modules with 4Mbit flash
memory.
