Spatial FOG Reference ManualPage 50 of 144Version 2.303/05/2018For more information on using Kinematica, please see the Kinematica ReferenceManual available for download from the Advanced Navigation website.10.14 RAIMRAIM stands for receiver autonomous integrity monitoring. It allows a GNSS receiver todetect and exclude both faulty and fraudulent satellite signals. Spatial FOG's internalGNSS is equipped with RAIM and it is enabled by default.10.15 HeaveSpatial FOG can provide vertical heave position at four diferent points on a ship.Spatial FOG's heave filter is always on and fully automatic. After power on, Spatial FOGrequires approximately 5 minutes for it's heave filter to converge upon an accuratesolution. Heave works without a GNSS fix, however best heave performance isachieved when Spatial FOG has a GNSS fix.By default Spatial FOG provides heave from the point at which the Spatial FOG unit ismounted, however it can provide heave at four diferent ofset points on the ship. Toset the heave ofsets, either use the heave configuration dialogue in Spatial FOGManager, see section 11.8.9.10.16 Environmental ExposureWhilst Spatial FOG is environmentally protected, there are clearly defined limits to thisprotection that must be adhered to for reliable operation.Spatial FOG is only protected when it's connector is mated and an IP67 SMA GNSSantenna is attached. When any of these connections are not made the unit ofers noenvironmental protection.Illustration 28: Spatial Dual post processing configuration
