INTRODUCTION
1.1 OVERVIEW
The GARMIN GPS 35LP is a complete GPS receiver, including an embedded antenna, designed for a
broad spectrum of OEM (Original Equipment Manufacturer) system applications. Based on the proven
technology found in other GARMIN 12 channel GPS receivers, the GPS 35LP will track up to 12
satellites at a time while providing fast time-to-first-fix, one second navigation updates and low power
consumption. Its far reaching capability meets the sensitivity requirements of land navigation as well as
the dynamics requirements of high performance aircraft.
The GPS 35LP design utilizes the latest technology and high level circuit integration to achieve superior
performance while minimizing space and power requirements. All critical components of the system
including the RF/IF receiver hardware and the digital baseband are designed and manufactured by
GARMIN to ensure the quality and capability of the GPS 35LP. This hardware capability combined with
software intelligence makes the GPS 35LP easy to integrate and use.
The GPS 35LP is designed to withstand rugged operating conditions and is completely water resistant.
The GPS 35LP is a complete GPS receiver that requires minimal additional components be supplied by
an OEM or system integrator. A minimum system must provide the GPS 35LP with a source of power
and a clear view of the GPS satellites. The system may communicate with the GPS 35LP via a choice of
two RS-232 compatible full duplex communication channels (-xVS series), or two full duplex CMOS
channels (-xVC series). Internal memory backup allows the GPS 35LP to retain critical data such as
satellite orbital parameters, last position, date and time. End user interfaces such as keyboards and
displays are added by the application designer.
1.2 FEATURES
The GPS 35LP provides a host of features that make it easy to integrate and use.
1) Full navigation accuracy provided by Standard Positioning Service (SPS)
2) Compact design ideal for applications with minimal space
3) High performance receiver tracks up to 12 satellites while providing fast first fix and low power
consumption
4) Differential capability utilizes real-time RTCM corrections producing 3-10 meter position accuracy
5) Internal clock and memory are sustained by a rechargeable memory backup battery. The battery
recharges during normal operation.
6) User initialization is not required
7) Navigation mode (2D or 3D) may be configured by the user
8) Two communication channels and user selectable baud rates allow maximum interface capability
and flexibility
9) Highly accurate one-pulse-per-second output for precise timing measurements. Pulse width is
configurable in 20 msec increments from 20 msec to 980 msec.
