JRC GPS模块
这款模块是为了兼容GARMIN 25LVS而设计的，所以接口跟25LVS的接口兼容
基于日本JRC 450 JZ GPS接收机制做的gps 模块
*通道数： 15ch(GPS)+1ch(Search only)
*灵敏度: -130dBm(在NAY-3600G天线接收级别)
*接受频率: 1575.42MHz(L1),C/A
*动态范围: >25dB
l 独立精度: 位置: 10m 2dRMS (无SA干扰,HDOP<=1.5)
l 定位时间：
Hot start 8 seconds (typ.)
Warm start 33 seconds (typ.)
Cold start 40 seconds (typ.)
l 速度: 0.04m/s RMS(无SA干扰, 角度: <0.14°(无SA干扰,速度为60km/h,HDOP<=1.5) 。
l DGPS: 位置:7m 2dRMS 。
l 1PPS精度:UTC±1微秒
l 备用3v电池，低功耗。
l 天线接口：BNC接口
l 数据处理：
1. 通过at89c2051单片机输出的话，只输出GPRMC这一条语句
2. 也可跨过AT89C2051单片机，输出完整NMEA0183的语句
选择输出可以通过改变输出接口的线序来实现
l 串行通讯：RS-232电平输出，可直接与电脑串口连接 波特率： 4800bps
