The antenna gives as much as 30-dB achieve for GNSS purposes in a single radome housing with a single SMA connector.
Answer for field-test necessities
The CAST-1000 duplicates GPS RF alerts and makes use of dual-frequency sign era know-how. This enables for duplicate testing within the laboratory or the sector and real-time or configured management. The CAST-1000 is cellular and moveable, which makes it the perfect answer for area check necessities. Producing GPS and GLONASS alerts with as much as 12 satellites in view, the CAST-1000 simulates alerts for satellites of P code on L1 and L2 and C/A code on L1. The GPS RF sign is dual-frequency and has a 12-channel configuration for any mixture of seen area automobiles. The system is very programmable — operators can select from an array of auto varieties and replicate dynamic movement for all types of automobiles, from terrestrial to aquatic, airborne to space-based. By using 6-DOF dynamic profile knowledge collected within the area and thru profile configuration, a trajectory may be created. The CAST-1000 additionally encompasses a efficiency analysis module, permitting for comparisons between uncooked and filtered knowledge.

For the geospatial business
The GNSS Surveyor cellular software offers location info and high quality place knowledge in actual time with sub-meter to centimeter accuracy. It connects to any exterior GNSS receiver by way of Bluetooth. Options embrace a one-touch configured command to speak instantly with the GNSS Bluetooth system; location info and high quality of the place knowledge in actual time with centimeter accuracy; GPS knowledge corresponding to place, peak, satellites and velocity; and constellation info for GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS satellites. It additionally features a direct IP function for real-time kinematic (RTK) corrections knowledge. An inner NTRIP shopper masses RTCM knowledge from the web. Location info is collected as latitude and longitude, altitude, velocity or tempo, bearing and UTC time. GNSS precision consists of international protection, centimeter-level accuracy, quick time to first repair, multi-constellation and multi-band, and highest safety. Navigation makes use of embrace floor robotics navigation, lane-level navigation, heavy machine navigation, industrial navigation and monitoring, and business UAV.

Slam know-how removes level cloud artifacts
The SLAM-based NavVis M6 Indoor Cellular Mapping System (IMMS) now mechanically detects and removes level cloud artifacts, together with shifting objects in static scenes. The newest IMMS launch removes artifacts from level clouds through the post-processing of scan knowledge (see earlier than and after picture above). Fringe factors and dynamic objects are two widespread forms of level cloud artifacts that have an effect on all 3D laser scanning units. The NavVis M6 IMMS makes use of laser scanners to seize a excessive quantity of measurement factors of an surroundings. With the newest software program replace, the algorithms utilized through the post-processing of scan knowledge makes use of the a number of observations to detect whether or not measurement factors truly exist within the bodily area. Whether it is decided that the purpose doesn’t exist and is as an alternative ensuing from the laser beam hitting an edge or an object shifting via the area, this level is routinely eliminated. The result’s a a lot cleaner, crisper level cloud that requires much less clean-up time in point-cloud modifying software program and that’s simpler to make use of for purposes similar to BIM modeling.
