The satellite navigation or satnav system is the system that offers autonomous geo spatial positioning it helps small electronic receivers to determine their location longitude latitude and altitude elevation to high precision using time signals transmitted along a line of sight by radio from the satellites. Dna is a long polymer made from repeating units called nucleotides each of which is usually symbolized by a single letter. Another right handed duplex model is a dna alternate dna. Gnss is used to pinpoint the geographic location of the user s receiver.
