broadcasted in navigation messages coded into the satellite signals, the time of transmission of the signal is also coded into the satellite signal. The difference between time of transmission and time of reception of the coded GNSS satellite signal gives the traveling time. The distance to a satellite can be obtained by multiplying the traveling time of the GNSS signal from the satellite to the users GNSS receiver by the speed of the GNSS signal (approximately 300,000 km/s). Examples of GNSS positioning

UNIT 1 NOTES Digital Computer A digital computer is an electronic computing machine that uses the binary digits (bits) 0 and 1 to represent all forms of information internally in digital form. Every computer has a set of instructions that define the basic functions it can perform. Sequences of these instructions. Component of Digital Computer: (1)CPU: The Central Processing Unit (CPU) or the processor is the portion of a computer system that carries out the instructions of a Computer, and is the

connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. It interconnects LAN’s. Analog technologies: information is translated into electric pulses of varying amplitude (waves). Digital technologies translation of information is into binary format (zero or one) where each bit is representative of two distinct amplitudes. Communication and media channels: Twisted pair cable: most prevalent, used almost all business telephone

Artificial Intelligence Artificial intelligence is an advanced branch of science which enables digital computers to perform complex tasks that are usually associated with requiring human intelligence. These tasks can vary from game playing to robotics. The best way to describe A.I is by comparing it to a human brain, digital computers consist of a network of switches and computers make decisions by using on/off switches. The basic element of the brain, the neuron also uses two state operations

environment, or another person. Data represents facts, objects and ideas that can be processed or manipulated with computer programs known as software. Most of this processing takes place in a component known as the CPU – central processing unit, or the computer’s brain. Memory is the area within a computer that temporarily holds data for processing while the computer’s storage area is where data is stored on a more permanent basis. Output is what is produced by a computer. Today’s computers work by loading
