A navigation system uses stored map data to calculate a course and detect a vehicle’s physical location by communicating with global positioning satellites. In aviation, navigation is a crucial component that is impacted by multiple parameters. Therefore, having a better navigation system can make the situation safer and more affordable.
The Global aircraft alternate navigation system market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Several different alternative navigation methods for military aircraft have been successfully tested by Honeywell. These new items are designed to support seamless navigation even when GPS signals are interrupted, obstructed, or unavailable. The different aircraft alternate navigation technologies are vision-aided navigation, magnetic anomaly-aided navigation, and celestial-aided navigation.
In India, Raytheon will unveil a brand-new satellite-based aeroplane navigation system. In addition to increasing safety, easing congestion, and enhancing communications, the new GPS-aided Geosynchronous Augmented Navigation System (GAGAN) might result in fuel cost savings for airlines of 20%.
The IntuVue RDR-84K radar system from Honeywell International Inc. may be included aboard Airflow, Inc.’s next-generation electric Short Takeoff and Landing (eSTOL) aircraft, according to a memorandum of understanding (MOU) the two companies signed.
Aircraft navigation has developed greatly as a result of global navigation satellite systems (GNSS), notably GPS. Even though the Instrument Landing System (ILS) is still the key tool for performing precision approaches, new satellite navigation technologies are also available.
With the use of the operational knowledge gained through ILS, Airbus has merged these new technologies with an interface that resembles ILS. A new certified cockpit avionics feature for operators of the A320 and A330 families, for line-fit and retrofit, known as a satellite-based/augmented landing system, is the most recent of these to be introduced (SLS).
By enabling steady approaches, particularly at airports without precision approach methods at main runways as a backup to ILS, SLS capabilities improves the operations of the airlines.
The likelihood that a “secondary airport” will have enough traffic to pay for the installation of radio-based ILS equipment on the ground is frequently lower. ILS, on the other hand, is frequently used at major airports and allows for precise tracking of the glidepath down to the runway decision height. It is particularly helpful in inclement weather or when there are impediments below the approach.
The aircraft is able to make precise ILS-like CAT1 approaches into the secondary airports in limited visibility thanks to its SLS capability and SBAS augmentation coverage in the sky.The GPS satellites, also referred to as the “Global Navigation Satellite System” in this context of aviation, transmit data to the multi-mode receiver (*MMR) of the aeroplane through its GPS antenna (GNSS).
In addition to these sources of location, “Satellite-Based Augmentation Systems” (SBAS), which transmit their signal via geostationary satellites, also provide overlay adjustments to the MMR. To account for potential ionosphere-induced position inaccuracies, the corrections are necessary for accurate approaches.
Another justification is to regularly check and validate the GPS signal’s overall integrity. The MMR of the aircraft also computes the precise horizontal and vertical guidance that may be broadcast to the electronic flight displays and autopilot in real-time.
