Leica SR 510
The Leica SR510 is a twelve channel, single frequency, survey receiver. Rugged versatile and very easy use, the SR 510 with Ski Pro L1 Software provides an easy entry to GPS surveying and a cost effective solution for many applications. The Leica SR510 receivers are based on Leica’s revolutionary ClearTrak technology providing the the highest quality satellite tracking, jamming resistance, and multipath mitigation. With an accuracy specification of five to 10mm+ 2 PPM The SR 510 is well suited for control, triangulation, traversing and photo control surveys. The SR510 was designed with an upgrade path in mind. Moving to dual frequency or RTK is simple and convenient.

Leica SR 520
The SR520 is a 24 channel dual frequency survey receiver. Rugged, light weight and very easy to use, the SR 520 with Ski-Pro software provides the accuracy required for geodetic control work. Utilizing Leica's revolutionary ClearTrak technology  the SR520 is capable of producing better than 3mm+.5ppm baseline accuracies when used with with a choke ring antenna,.  Used with the small, lightweight AT502 antenna with built in groundplane, accuracy of 5mm+1PPM is achieved, providing a very effective tool for local control  surveys. 

Leica SR530
The flagship of the System 500 family of products, the SR530 is a 24 channel, dual frequency receiver with on-board RTK.  It provides outstanding performance for every type of GPS surveying.

The SR530 utilizes the full spectrum of Leica's revolutionary ClearTrak technology with advanced signal processing, anti-jamming protection and patented multipath mitigation techniques.  There is simply no better receiver in tough environments such as tree cover or urban canyons. 

Designed with RTK in mind, the SR530 can be used as a reference or a rover.  It can be set to send or receive Leica, RTCM, or Trimble CMR correction formats.  Simply connect a radio modem, digital cell phone, or CDPD modem for full RTK capability.  The advancement of today's modern data links extends the effective range of RTK.  The SR530 is ready to provide survey grade accuracy at ranges of 25 miles from the reference station. No other survey grade receiver can match this capability.

If you are concerned about possible errors in RTK surveying, the SR530 puts your mind at ease with its exclusive Checkmate technology.  Under Checkmate, when the receiver begins the initialization process, the ambiguity search is performed twice to insure consistency.  As your job progresses Checkmate uses the multitasking capability of the SR530 to constantly recheck the status of the integer ambiguity.  The integrity of your solution is literally checked more than twice per minute as your work progresses during the day.  The result of this rigorous checking is that we are more than 99.99% confident that you will get the right answer all the time every time.  No other survey grade receiver can provide this level of reliability.

The user gets access to all this technology without sacrificing ease of use. One button access to functions is provided via user defined function keys.  The inclusion of an on board database for point management and for coordinate system management makes data collection easy.  Advanced applications are available including roadstaking and dtm stakeout.  The SR530 is very flexible tool for all kinds of surveying work.
