You don't need a magnetic compass for this. The Larus sensor unit automatically determines the calibration of the magnetic compass during circling flight, so that it can then be used to measure the magnetic heading in straight flight. Together with the adjustable magnetic declination, true heading (relative to true north) can be measured with an accuracy of about 1-2 degrees.<\/p>\n<\/div><\/div><div class=\"et_pb_text_11 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><p style=\"font-weight: 400;\">With LARUS Dual-GNSS, the accuracy of the heading can be improved to approx. 0.05 degrees by using a D-GNSS \"compass\" (2 coupled differential GNSS receivers, here uBlox F9P).<\/p>\n<p style=\"font-weight: 400;\">The flight attitude measurement can be used for an artificial horizon as well as for the precise display of the current drift angle (track \u2013 heading).<\/p>\n<\/div><\/div><div class=\"et_pb_image_7 et_pb_image et_pb_module et_block_module\"><span class=\"et_pb_image_wrap\"><img decoding=\"async\" src=\"https:\/\/stefly.aero\/wp-content\/uploads\/2023\/03\/Berechnung-Steuerkurs.jpg\" width=\"1500\" height=\"393\" srcset=\"https:\/\/stefly.aero\/wp-content\/uploads\/2023\/03\/Berechnung-Steuerkurs.jpg 1500w, https:\/\/stefly.aero\/wp-content\/uploads\/2023\/03\/Berechnung-Steuerkurs-1280x335.jpg 1280w, https:\/\/stefly.aero\/wp-content\/uploads\/2023\/03\/Berechnung-Steuerkurs-980x257.jpg 980w, https:\/\/stefly.aero\/wp-content\/uploads\/2023\/03\/Berechnung-Steuerkurs-480x126.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1500px, 100vw\" class=\"wp-image-12305\" title=\"Berechnung Steuerkurs\" \/><\/span><\/div><\/div><\/div><div class=\"et_pb_row_7 et_pb_row et_block_row\"><div class=\"et_pb_column_12 et_pb_column et_pb_column_1_2 et_block_column et_pb_css_mix_blend_mode_passthrough\"><div class=\"et_pb_text_12 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><p style=\"font-weight: 400;\"><strong>Pressure Sensors<\/strong><\/p>\n<p style=\"font-weight: 400;\">The Larus sensor box contains pressure sensors for measuring static pressure and dynamic pressure.

This is particularly high priority for LARUS Essential. In particular, the correct operation of the inertial measuring unit IMU, which among other things measures the magnetic induction, is severely impaired by magnets, changing magnetic fields or iron parts. We recommend keeping the LARUS sensor unit as far away as possible (at least 20 cm), especially from speakers and magnets (often contained in GPS \/ GNSS antennas, simply check with magnets). In addition, the fastening elements in the immediate vicinity of the sensor should be made of stainless steel, brass, plastic, aluminum or fiber composite materials and the usual nuts and bolts made of steel should be avoided. Iron parts are unsuitable because they generate a variable interference field with every movement of the aircraft.<\/p>\n<p style=\"font-weight: 400;\">The GNSS antenna, on the other hand, is not sensitive to magnetic fields.<\/p>\n<\/div><\/div><div class=\"et_pb_text_24 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><p style=\"font-weight: 400;\"><strong>Explanations regarding LARUS Dual-GNSS<\/strong><\/p>\n<p style=\"font-weight: 400;\">With LARUS Dual-GNSS, on the other hand, it is important that the two GNSS receivers are at least 1.0 meters apart.<\/p>\n<p style=\"font-weight: 400;\">The master GNSS antenna should be mounted on the inside of the fuselage tube (luggage compartment \/ end of the canopy) approximately above the center of gravity of the aircraft. Because the shorter the distance between the antenna and the center of gravity, which is also the center of rotation of the aircraft around the pitch axis, the less the influence of pitching movements (forward or backward movement of the stick) on the measured altitude.<\/p>\n<p style=\"font-weight: 400;\">The second antenna (slave GNSS antenna), on the other hand, is mounted at the level of the instrument panel or in front of it in the nose of the aircraft.<\/p>\n<p style=\"font-weight: 400;\">For all GNSS antennas, it is important that the laminate above the antenna is made of GRP and not CFRP, otherwise the electrical conductivity of carbon fibers would cause the attenuation between the GNSS satellite and the receiver in the aircraft to be too great. In the case of aircraft with a CFRP fuselage, however, mounting the antennas in the front and rear area of the canopy can also be considered, provided the antennas are then at a sufficient distance (approx. 1.0 m) from one another.<\/p>\n<\/div><\/div><\/div><\/div><div class=\"et_pb_row_16 et_pb_row et_block_row\"><div class=\"et_pb_column_26 et_pb_column et_pb_column_4_4 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\"><div class=\"et_pb_text_25 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><p style=\"font-weight: 400;\">How is the information presented in XCSoar?<\/p>\n<\/div><\/div><\/div><\/div><div class=\"et_pb_row_17 et_pb_row et_block_row\"><div class=\"et_pb_column_27 et_pb_column et_pb_column_1_2 et_block_column et_pb_css_mix_blend_mode_passthrough\"><div class=\"et_pb_text_26 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><p style=\"font-weight: 400;\"><strong>OpenSoar with LARUS driver<\/strong><\/p>\n<p>In order to clearly present the results of the calculations of climb values, wind and position in space, Uwe Augustin has integrated a driver for LARUS into OpenSoar. The variometer display known from XCSoar uses the precise LARUS data. XCSoar continues to produce the vario sound, although no speed-to-fly option is currently implemented.<\/p>\n<p>The fact that LARUS is on board is revealed when you look at the display. You will see two separate wind arrows, which are shown directly in the moving map. In this way, the direction and strength of the current wind and the wind averaged over a longer period of time are visualized. In addition, new wind-related info boxes are available.<\/p>\n<p>Another novelty is the artificial horizon, which is displayed on a separate page in OpenSoar. It is helpful, for example, to check the correct function and calibration of the IMU after installing the sensor unit.<\/p>\n<p>Link to OpenSoar: <a href=\"https:\/\/opensoar.de\/releases\/\" target=\"_blank\" rel=\"noopener\">https:\/\/opensoar.de\/releases\/<\/a><\/p>\n<p style=\"font-weight: 400;\"><strong>LARUS data in a separate round instrument<\/strong><\/p>\n<p>Thanks to OpenSoar, it is already possible to use a large part of the functionality of LARUS.
