This is particularly advantageous at high airspeed in level flight. As the wind triangle illustrates, at an airspeed of 200 km\/h, 2\u00b0 corresponds to a 7 km\/h inaccuracy in the crosswind component, while 0.05\u00b0 corresponds to only a 0.2 km\/h inaccuracy.<\/p>\n<\/div><\/div><div class=\"et_pb_text_5 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;\">In addition, the accuracy of the dual GNSS version is not affected to the same extent as LARUS Essential if iron parts or magnetic fields in the vicinity of the LARUS sensor unit cannot be avoided due to the installation situation.

Ideally, the LARUS sensor unit is also mounted in such a way that it is roughly horizontal in normal flight.<\/li>\n<li>The GNSS antennas must be mounted in such a way that there is \"line of sight\" to as many satellites as possible. For this reason, they must be installed in the instrument panel or fuselage tube approx. in-flight-horizontal and above electrically conductive materials.

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_9 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_8 et_pb_row et_block_row\"><div class=\"et_pb_column_12 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_10 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;\"><span>LARUS License<\/span><\/p>\n<\/div><\/div><\/div><\/div><div class=\"et_pb_row_9 et_pb_row et_block_row\"><div class=\"et_pb_column_13 et_pb_column et_pb_column_1_2 et_block_column et_pb_css_mix_blend_mode_passthrough\"><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;\">Larus hardware is licensed accordingly to <strong> <a href=\"https:\/\/github.com\/larus-breeze\/hw_sensor\/blob\/master\/LICENSE.md\" rel=\"nofollow\">Creative Commons NonCommercial Share-alike 4.0 International<\/a>,\u00a0<\/strong>Larus software accordingly to <a href=\"https:\/\/github.com\/larus-breeze\/sw_sensor_algorithms\/blob\/main\/LICENSE\"><strong>GNU General Public License v3.0<\/strong><\/a>.<\/p>\n<p style=\"font-weight: 400;\">License fees ensure long-term further development.\u00a0<\/p>\n<\/div><\/div><\/div><div class=\"et_pb_column_14 et_pb_column et_pb_column_1_2 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\"><div class=\"et_pb_image_4 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\/07\/LARUS_LOGO-k.png\" width=\"500\" height=\"541\" srcset=\"https:\/\/stefly.aero\/wp-content\/uploads\/2023\/07\/LARUS_LOGO-k.png 500w, https:\/\/stefly.aero\/wp-content\/uploads\/2023\/07\/LARUS_LOGO-k-480x519.png 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 500px, 100vw\" class=\"wp-image-13253\" title=\"LARUS_E-Vario_Windberechnung_Logo\" alt=\"LARUS_E-Vario_Windberechnung_Logo\" \/><\/span><\/div><\/div><\/div><\/div><div class=\"et_pb_section_1 et_pb_section et_section_regular et_block_section\"><div class=\"et_pb_row_10 et_pb_row et_block_row\"><div class=\"et_pb_column_15 et_pb_column et_pb_column_4_4 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\"><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Umbau der Sensorbox eines LARUS Essential auf ein Larus-Dual-GNSS.
