In aerial mapping payloads the cables need to connect the devices to a power source, each other, and data loggers if you are using them, without affecting the airframe\u2019s ability to function (for instance not causing the rotors to foul in a quad-copter drone). For land-based mappers, the most challenging element is likely connecting the LiDAR and GNSS\/INS. This is because the LiDAR has to be mounted on the outside of the vehicle, while the GNSS\/INS is often mounted on the inside. <\/span><\/p>\n<p><span data-contrast=\"auto\">OXTS offers a bespoke roof mount which solves this problem by enabling you to mount your GNSS\/INS outside the vehicle with your LiDAR; if you choose not to use this, we generally pass the cables through a window or the boot, and tape them to the roof so that they do not come loose during driving. But ultimately as long as you can secure the cables so they don\u2019t get damaged by the doors, come loose during driving, and don\u2019t put undue stress on the connections, then you should be fine.<\/span><\/p>\n<p><span style=\"color: #c11722;\"><b>Summary:<\/b>\u00a0<\/span><\/p>\n<ul>\n<li><span style=\"color: #c11722;\">Decide whether your GNSS\/INS and surveying sensor will be powered via battery or the surveying platform\u2019s own power (such as the 12v outlet on a car)<\/span><\/li>\n<li><span style=\"color: #c11722;\">Cables need to be long enough to comfortably connect all the components together, but not so long as to affect the platform\u2019s operation.

However, in many cases, as soon as GNSS disappears, position drift can quickly get out of hand, rendering data unusable. The true value of a mobile mapping system comes from its ability to collect accurate data, both with and without GNSS. To combat position drift, the OXTS gx\/ix algorithm tightly-couples GNSS and IMU data to ensure position drift is kept under control during a survey.<\/p>\n<h5 aria-level=\"2\"><span style=\"color: #c11722;\"><strong>We\u2019re here if you need more support<\/strong><\/span><\/h5>\n<p><span data-contrast=\"auto\">Our aim when designing our GNSS\/INS devices was to make them as simple to set up as possible for a high-precision sensor.\u00a0But we know that different mobile mapping setups create unique circumstances and challenges that don\u2019t always have an obvious solution.
