GLONASS Tracking: L1/L2C/A, L1/L2P Full Cycle Carrier.GPS Tracking: L1C/A,L1/L2/L2C - Upgradable to L5.So what gives? What is the difference? Trimble SPS882 Specifications And both receivers, according to Trimble’s literature, are “committed to the next generation of modernized GNSS configurations by providing Galileo-compatible products, well in advance of Galileo system availability”. Both receivers list 1, 2, 5, 10, and 20 Hz positioning capability as well as CMR+, CMRx, RTCM 2.1, RTCM 2.3, RTCM 3.0, RTCM 3.1 input and output protocols.īoth receivers are VRS capable and both have 57MB of internal data storage (for static survey). There is a 5 mm difference listed in vertical accuracy and 2 mm in horizontal, but baseline lengths are not mentioned on either datasheet - which is the most likely reason for the difference. Both have Bluetooth, Lemo and serial ports for comminication. Per the datasheets, both receivers list the same shock, vibration, and IP67 ratings. We started with the datasheets provided on Trimbles website Both receivers use Trimble's Maxwell 6 chip's and have 220 channels allowing both receivers to track and provide corrections for up to 44 satellites. As the popularity of GPS and SCS900 grew, Trimble decided to divide the two groups with the purpose of developing products that better meet their customer’s needs. However, with the popularity of GPS growing in early 2000, Trimble realized that there was a demand for GPS for the non-surveyor, so they developed an easier to use software called SCS900 (Site Controller Software) for the Construction market. Most surveyors that use Trimble products are familiar with Survey Controller software and have formal education in surveying. The focus started with the controller software. The purpose of dividing the two markets is to provide better focus on the individual needs of their customers. The Survey/ Geospatial group and the Construction - Heavy Civil group. To get an understating why Trimble has produced two different GNSS receivers, we need to understand that there are two separate groups within Trimble. At we receive a lot of questions regarding the differences between the Trimble R8 Model 3 vs SPS882 receivers, so we decided to put them to the test to determine which receiver you should buy.
