1. Introduction

1.1 Overview

EverMore series GPS module ST-K700 is a high sensitivity ultra low power consumption cost

efficient, compact size; plug & play GPS module board designed for a broad spectrum of OEM system

applications. This product is based on the proven technology found in 16 channel GPS receivers and

NEMERIX chipset solution. The GPS module receiver will track up to 16 satellites at a time while

providing fast time-to-first-fix and 1Hz navigation updates. It is far reaching capability meets the

sensitivity & accuracy requirements of car navigation as well as other location-based applications,

such as AVL system. Handheld navigator, PDA, pocket PC, or any battery operated navigation system.

The ST-K700 design utilizes the latest surface mount technology and high level circuit

integration to achieve superior performance while minimizing dimension and power consumption. This

hardware capability combined with software intelligence makes the board easy to be integrated and

used in all kinds of navigation applications or products. The module communicates with application

system via RS-232 level with NMEA0183 protocol.

1.4 Start-up Modes

Definitions

DESCRIPTION

Cold Start

The Cold Start takes the longest startup time among EMT GPS receivers. In

this scenario, the receiver has no acknowledgment on the last position, time,

and satellite constellation. The receiver is initiated to search blindly for satellite

signals in the cold start mode.

nother situation is that when no backup battery is connected, the GPS

receiver will be in the cold start mode and there is no data stored in SRAM.

Execute cold start of the test tool when first use. By this way can speed up

position fix time.

Warm Start

In this scenario, the receiver was off less than one week but more than 2-hour

time.

The receiver knows its last position, time and almanac because it has a

backup battery to keep current almanac, position and time stored in SRAM.

In the warm start mode, the receiver can quickly acquire satellites and get a

position fix faster than it does in the cold start mode.

Hot Start

In this scenario, the receiver was off less than 2-hour time. With the back up

battery connected and the current almanac, position, time and ephemeris

stored in SRAM, the receiver applies its last ephemeris data to calculate and

get a position fix.

Reacquisition

In the reacquisition mode, the receiver takes time to lock on satellites if

buildings or obstacles are blocking the signals for a short while.

This is very common in urban areas, but please be noted that reacquisition

time has nothing to do with the time-to-first-fix (TTFF).
