Why is there no information about the Inmarsat and Iridium networks that a lot of aircraft already use?
Why is there no information about the Inmarsat and Iridium networks that a lot of aircraft already use? ADS-B is fantastic for fast, accurate position data, and apart from the hardware is essentially 'free' for an aircraft to make use of. Satellite transceivers are also relatively cheap (a few thousand dollars), but the main expense is in sending data to and from the transceiver. This cost can be alleviated by having the transceiver programmed to send a position report from every 30 seconds to every few minutes. It's also possible to switch between ADS-B, and satellite networks when in range of ADS-B ground stations to make things more efficient. Satellite tracking fairly ubiquitous in Australia, New Zealand, the UK, and the US – there's even some consumer level products such as SpiderTracks [ http://www.spidertracks.com/collections/hardware/products/ha... ] which provide similar SBD modems (Iridium network) to those used in commercial aviation. I'm guessing it's just not a requirement for aircraft operating in that airspace to use satellite tracking, as there was even less data about Malaysia Airlines flight MH 370.
