GPS Receiver Module Specification
June 2008
General Description
The DeLorme GPS2058 module combines the STMicroelectronics high sensitivity STA2058 (Teseo) GPS
baseband chip with the STA5620 Low Power GPS RF front end to form a complete high performance GPS
receiver module. The GPS2058 is an ideal solution for consumer, Handheld, PND (Portable Navigation),
in-vehicle Navigation and Telematics systems. The GPS2058 is offered with a complete GPS firmware
which performs all basic GPS operations including tracking, acquisition, navigation and data output with
no need of external memories. SBAS (WAAS and EGNOS) features are also supported.

Functional Description
The DeLorme GPS2058-10 module simplifies embedded applications of GPS-based information systems. The important
components of a basic GPS receiver subsystem are LNA, SAW Filter, RF front end, power conditioning, and the GPS baseband
receiver itself. All these subsystems have been built into the DeLorme GPS module to eliminate the cost and time needed
for the user to develop them independently. In simple terms, the user must connect an active or passive antenna, provide a
power source, and connect the module to a host system via a serial port (or USB) to produce GPS positional data and enable
a complete GPS receiver system. Designed for PCB mounted application, the module has a tiny 16x16mm footprint for use in
small form-factor end applications such as portable systems.
For fast startup times, the Teseo baseband features an onboard 16KB of FLASH memory for storing the satellite almanac and
ephemeris data, and this data is saved and restored automatically as a background process. This eliminates the need for
additional external memory and eliminates any programming to save and recover this data.
The Pulse-Per-Second (PPS) output provides an accurate timestamp, synchronized to Universal Coordinated Time (UTC). The
time is established via communication with one satellite and verified with a second satellite. If a fix is obtained and lost the PPS
will continue to run as long as the time is valid. No PPS pulse indicates the time is not valid.
