At ComNav Technology, we highly value creativity and innovation! We started making our GNSS Receivers by designing and producing our own Chipset and OEM modules. We firmly believe our GNSS technology innovations make your work easier, safer and more efficient.
The GNSS Constellations incorporated Beidou Global and Galileo signals in the recent years so almost everywhere, a GNSS receivers can track more than 35 satellites. At the same time, triple frequencies are now a standard for each constellation. All those are making GNSS surveys much faster than before and accurate.
What remains a hassle is to measure the offset points (points that cannot be surveyed with the pole tip). Attempts has been in the past by using camera and photogrammetry, laser and compass. However, direct measurements to these points are much easier and accurate.
We solved that problem with the Venus Laser IMU RTK. These three combined technologies into a handy housing are the game changer for surveyors but also for anyone interested in taking 3D positions everywhere.
After few years development, the first Venus RTK is coming out!
As a surveyor, it’s often challenging to survey in obstructed area. For instance, imagine to survey in a trench or sewage pit, on top of buildings or earthworks, beside fences or walls or water, etc. Field measurements and stakeouts at dangerous areas are inevitable in the surveyor’s jobs. These include hidden points, utility piping across a river, manhole covers on the road and slopes, railway tracks, polluted area etc.
In all these scenarios, the Venus Laser RTK is the winning equipment.
The Venus laser RTK is equipped with a millimeter-level distance meter on its bottom. It sends a laser pulse towards an object and measures the time taken by the pulse to be reflected off the object and returned to the emitter to determine precisely the distance between the receiver and the object.
The laser module embedded into the Venus receiver can dynamically detect light intensity, adjust signal amplification factor, then optimize signal-to-noise ratio, ensuring high-quality and high-frequency data output under various lighting conditions.
The Venus laser RTK comes with ComNav 3rd generation IMU to obtain the tilt angle. We consider the line connecting the GNSS antenna phase center and the laser point as a vector (vector L), in the local coordinate system (n-system), If we align the Z-axis of the accelerometer of the inertial device (IMU) parallel to vector L, and set the carrier coordinate system (b-system) parallel to the sensitive axis of the 3-axis accelerometer, with the origin at the intersection of the sensitive axis, a right-handed coordinate system is formed.
Therefore, no matter how the module moves with the receiver, vector L in the b-system is a constant vector. By utilizing this deterministic relationship and performing real-time calculation with a GNSS/INS integrated navigation system, we can obtain the heading and tilt angle.
The laser is replacing the bulky pole for measuring distances and therefore breaks the usual limitations.
Simply take the Venus Laser RTK out of your pocket and start working right away with the correction services from your GNSS RTK network to get positions fixed and use the laser to shoot to the points you need to survey.
The compact design of this product looks like a mug, and its 380g weight makes it convenient to be carried lightly around.
As for the accuracy, on the pole mode, it has tilt compensation up to 60 degrees with an accuracy of 2.5 cm; in laser mode, it achieves an accuracy of 5.5 cm in handled mode. Thus, Venus delivers precise 3D coordinates to everyone, anywhere, and safely.
“Safely” here refers not only to increase the user’s safety, especially in dangerous situations, but also the laser’s safety. Because Venus uses a laser of 3R Class that is considered safe when handled carefully. Normally, it won’t hurt the eyes in a momentary exposure and can be sold as “pointers” or for pointing purposes in the USA.
When “GNSS + INS” RTK is becoming standard, ComNav Technology solves the offset points issue with direct measurements. It is clearly an impressive innovative way and the next measuring revolution: the first rodless GNSS receiver!
And because of its extensive application scenarios, the Venus Laser has been made for everyone: surveyors, GIS operators, city planners, architects, engineers, construction managers, gardeners, students at school, police for surveying crash scenes, road managers …
