RTK Protocol Choices Give You More Options
April 7, 2011
MyWay RTK is offering two different types of message protocols in order to be compatible with as many different RTK systems as possible. Older RTK receivers, often times referred to as “Legacy” equipment, most commonly use what is known as CMR or CMR+ protocol. This message type transfers smaller bits of information, and only transfers corrections from GPS satellites. Newer equipment, capable of GPS and GLONASS corrections, needs a message that can handle more data bits when there is more information to be transferred. This “newer” protocol is known as RTCM 3.0.
MyWay RTK offers both CMR+ and RTCM 3.0 mount points for use with various types of equipment. These two protocols will cover nearly all of the various RTK receivers on the market that will accept “standard protocols”. Equipment that will not accept these messages use what is known as a “proprietary protocol”, meaning they will only work with base stations produced by the same manufacturer as the receiver. The choice of two mount points with two different protocols gives you more options and is just another way that MyWay RTK is striving to be the leader in open source, brand neutral RTK corrections.
