What is NTRIP?
NTRIP (Network Transport of RTCM via Internet Protocol) is a protocol for transmitting Real Time Kinematic (RTK) GPS data over the Internet. RTK GPS is a high-precision GPS technology that can provide accuracy down to a few centimeters. NTRIP is used to transmit RTK GPS data from a base station to a mobile receiver, allowing the mobile receiver to calculate its precise position in real-time. NTRIP is commonly used in surveying, mapping, and other applications where precise location information is required. It can be used in conjunction with a variety of GPS receivers and other surveying equipment.
History of NTRIP
NTRIP was developed in the late 1990s as a way to transmit RTK GPS data over the Internet. Prior to the development of NTRIP, RTK GPS data was typically transmitted using dedicated radio links, which were expensive and limited in range. NTRIP was designed to provide a more cost-effective and flexible alternative to radio links, by allowing RTK GPS data to be transmitted over the Internet.
The first version of the NTRIP protocol was released in 2000, and the protocol has since undergone several updates. In the early 2000s, NTRIP began to be widely adopted in the surveying and mapping industry, and it has since become the standard protocol for transmitting RTK GPS data over the Internet. NTRIP is now used in a variety of applications, including surveying, mapping, precision agriculture, and autonomous vehicles.
What is RTK?
Real Time Kinematic (RTK) GPS is a high-precision GPS technology that can provide accuracy down to a few centimeters. It is used in a variety of applications where precise location information is required, such as surveying, mapping, and construction.
RTK GPS works by using a stationary reference station, known as a base station, to transmit correction data to a mobile receiver. The correction data is used to compensate for errors in the GPS satellite signals, allowing the mobile receiver to calculate its position with a high degree of accuracy. RTK GPS systems typically use two frequencies (L1 and L2) to provide even greater accuracy.
In order to use RTK GPS, the base station and mobile receiver must be connected, either via a radio link or through a network connection such as NTRIP (Network Transport of RTCM via Internet Protocol). Once connected, the mobile receiver can continuously calculate its position in real-time as it moves. RTK GPS is commonly used in conjunction with specialized surveying equipment such as total stations and levels.
