How can that be? If you allow refunds, you are losing sales. The short-term answer is perhaps. The objective of every business is to increase profits for the long - term.If you have a no refund policy, many customers will

Everyone is familiar with the traditional models for making money. There are a few options available: Either you work for somebody as an employee, or you work as a self-employer, or you run some sort of business. Each of these h
A. By Purposes
1. Aviation GPS receiver: It is mainly used in aviation of moving carriers. It tells locations and speed of the moving carrier in real time. Measured psychologically with C/A number, so its single positioning is less precise which is about +-25 MM. If affected by SA, the differences can be +-100 MM. The kind of GPS receivers is less expensive and widely used in various industries.
2. Ground GPS receiver: It is mainly used in precise ground and engineering measurement. It uses the value of carrier phase to measure the relative position, so the result is precise. The receiver is built complicatedly, so the price is highers.
3. Time transfer GPS receiver: It transfer time by highly precise satellite. It is usually used in the the observatory and wireless communication.

Rising house prices in the UK (and other countries) have made it very difficult for first time buyers in the UK. The ratio of house price to earnings has risen significantly. With average house prices rising to over ?100,000 man
B. By Frequency
1. Single-channel GPS receiver: It only receives signal of L1 carrier wave and positions by value of carrier phase. It can't eliminate the affect of ionosphere delay, so it is only applicable for precision position of ultra short base line less than 15 KM.
2. Double-channel GPS receiver: It can receive carrier signals of both L1 and L2. With its differences to ionosphere delays, the delay of electromagnetic wave signal caused by ionosphere can be eliminated. Therefore, it can be used in precision position for thousands of kilometers.
C. By Channels: GPS receivers can receives signals transmitted from multiple GPS satellites at the same time. It uses antenna singal channel to separate the signals received and track, handle and measure individual satellite. The channels are divided into multi-channel receiver, serial channel receiver and multi-channel receiver.
