Introduction
In the archaeological site, the most afraid of not digging things, but “digging but can not find the north” – a piece of broken porcelain, half a piece of tile, as long as the coordinates are off by one centimeter, may be the history of a whole layer of misjudgment. Norwegian Institute for Cultural Heritage (NIKU) will be only 7 grams of Septentrio mosaic-X5 GNSS receiver used in archaeological research. Do not look at it only 31 × 31 × 4 mm, but stuffed into the 448 hardware channels, can simultaneously “listen to” GPS, Beidou, Galileo, GLONASS, QZSS, NavIC six constellations of all civil and new signals; in the traditional receiver has long been “lost stars! In the city canyon, the bottom of the well, the dense forest, the root of the city wall, it still locks 30+ satellites stably, with 99.9% RTK fixation rate, planar accuracy of 0.6 cm + 0.5 ppm, and vertical accuracy of 1 cm + 1 ppm. in other words, even if your probe digs into the 8-meter-deep well, it can still “nail” the 800-year-old skull to the ground. “In other words, even if you dig an ancient well 8 meters deep, it can nail the skull of 800 years ago to the coordinates of the horizontal and vertical elevation without a difference of one centimeter, and then return to the office and import it into GIS directly, and the layers will be aligned automatically, so you don’t need to carry a total station to make up measurements in the middle of the night anymore.
Why the mosaic‑X5 Performs in “Archaeological Hell”
GNSS+ Anti‑Jamming Technologies
The answer is hidden in Septentrio’s exclusive GNSS+ “anti-jamming four-pack”. The first is Septentrio AIM+ anti-interference technology, the industry’s strongest anti-spoofing, anti-interference engine, 450 MHz walkie-talkie face, drone mapping, high-voltage corridor, stone crusher spark plugs are fired, it can still be cut out in real time narrow-band, wide-band, swept frequency, impulse interference, to maintain the Fix; the second is the Septentrio LOCK + anti-vibration technology, in the high-frequency vibration still It can can level modeling real-time correction, heavy rain day As usual, it gives More considerate What’s more, it is 0.6 W ultra-low power consumption, a piece of field charging treasure can work for a long time; operating temperature -40 ℃ to +85 ℃, from the Arctic tundra to the Sahara sand layer can be posted on the board that is used; 100 Hz high-update, <10 milliseconds of latency, the UAV low altitude sweep shooting, handheld RTK backpacks while walking and measuring, the screen and coordinates are smooth and lag-free. Compared with traditional “big brick” receivers, mosaic-X5 cuts down the size, power consumption and robustness to the extent that archaeologists can “carry it with them and stick it on their hands” – you can solder it to the main body of the drone. You can solder it to the main board of the drone, put it into the back of a handbook, or even stick it directly on the top of the probe ruler, and finish the patch in seconds.
Triple‑Mode GNSS Workflow
What really makes the archaeological team excited is the Septentrio mosaic-X5 GNSS receiver’s “one board, three to eat” compatibility strategy: on-site, there is a local base station centimeter-level RTK; away from the base station of 10 to 100 kilometers, automatic switching regional PPP-RTK, which can achieve centimeter-level GNSS accuracy; and run to the overseas, NIKU’s report card in Sverresborg Castle in Trondheim is the best advertisement: they “nailed” all the human bones, arrowheads, ceramic fragments, animal bones and architectural components in the bottom of the well into the GIS, and then returned to the laboratory. Laboratory and Laser scanning point cloud superposition, the average error value of 0.8 cm, the largest 1.2 cm, a whole generation of equipment than the previous generation to narrow 70%, grabbed 3 days of work; previously used a brand of consumer-grade receiver, deep well signal is wall reflection floating into “twist”, a day to retest three times still do not dare to set the layer position, now mosaic-X5 direct Now mosaic-X5 can directly “pass once”. Stick mosaic-X5 into your drone, handbook, backpack or probe ruler, it is the same as the “laboratory grade coordinates” into the exploration backpack – from now on, every tile, every human bone, every coin, can be in the next 800 years location! Never “deviation”, so that history is really “a centimeter are not bad”. The romance of archaeologists is to pin the disappeared civilization back to the earth; Septentrio mosaic-X5 GNSS receiver is the “time and space nail” that never rusts.
