Multi2Carrier-Measurements
利用GNSS 进行高精度导航定位的前提是正确固定载波相位观测值的整周模糊度。由Galileo 系统的4 个载波观测值可以
形成诸多有良好特性的组合观测值,利用这些组合观测值,结合MCAR 方法,可以有效地确定整周模糊度。(The use of high-precision GNSS navigation and positioning the premise is correct carrier phase observations fixed integer ambiguity. May consist of four carriers observations Galileo system
There are many good characteristics to form a combination of observations using a combination of these observations, combined with MCAR method can effectively determine the integer ambiguity.)

Timer_key_1602
利用MSP430单片机实现5分钟倒计时。用Timer_A实现1s定时，4位共阳型数码管显示时间，显示格式为：“x-xx”，分别代表“分”、“十秒”和“秒”。每隔1s，倒计时器的时间减1，倒计时从4分59秒开始计时，至0分0秒结束，停止计时。(MSP430 microcontroller is used to realize 5 minute countdown. Timer_A is used to realize 1s timing and 4-bit common-sun digital tube display time. The display format is "x-x x", representing "minutes", "ten seconds" and "seconds" respectively. Every 1s, the countdown time is reduced by 1. The countdown time starts at 4:59 seconds and ends at 0:0 seconds.)

113、程序
说明： 113、基于51单片机老人生理智能监控GSM短信
本设计由STC89C52单片机电路+火焰传感器电路+加速度传感器+心率传感器电路+SIM800A_GSM模块电路+电源电路组成。
该系统实时监测老人是否跌倒，是否周围有火以及心率情况。
1、如果火焰传感器检测到火焰，则GSM向特定手机发送：Fire！
2、如果ADXL345检测到老人跌倒了，则GSM向特定手机发送：Fall！
3、如果心率传感器检测到老人心率高于120，则GSM向特定手机发送：High Heart！
4、注意本设计一次上电上述情况每个只能触发一次上报短信，不会连续发送，防止反复发送，请放心使用。
5、短信处理过程有GSM信号灯指示。
6、GSM模块是SIM800A，该模块和SIM900A电路程序完全兼容外观外形一模一样。(GSM SMS for elderly physiological intelligent monitoring based on 51 MCU
This design consists of STC89C52 MCU circuit + flame sensor circuit + acceleration sensor + heart rate sensor circuit + sim800a_ GSM module circuit + power supply circuit.
The system monitors whether the elderly fall down, whether there is fire around and heart rate in real time.
1. If the flame sensor detects a flame, the GSM sends: fire!
2. If adxl345 detects that an old man has fallen, the GSM sends a specific mobile phone: fall!
3. If the heart rate sensor detects that the heart rate of the elderly is higher than 120, the GSM sends a message to a specific mobile phone: high heart!
4. Pay attention to the design of a power on, each of the above conditions can only trigger a report SMS, will not be sent continuously, to prevent repeated sending, please rest assured to use.
5. SMS processing process is indicated by GSM signal light.)
