Vref+5 is spot on. ADSB proved to be an utter waste of money in terms of accident prevention as evidenced by the Mangalore crash and the loss of four lives, If that same time and money had been spent on proven WAAS technology, Lockhart wouldn’t have happened.
‘’So we still haven’t got WAAS because some Richard craniums in Canberra decided to wait for “second generation” WAAS? Not only have we lost lives in Aviation, we have forgone at least ten years of cost savings in the mining, agriculture and road transport sectors as well.
From the Geosciences website; they are as ponderous as an elephant and as brainless as a flea. Why didn’t we invest 20 years ago?
The SBAS test transmission services
The test transmission service that was part of the SBAS test-bed project will be discontinued after 31 July 2020. This service was intended for testing and development purposes only and is not a permanent SBAS for the region. We anticipate a similar test transmission service to resume in 2021 at the latest, and this will be developed to become a fully operational SBAS for the Australasian region by 2023. The new system will be called the Southern Positioning Augmentation Network.
The economic benefits
To evaluate the effectiveness and application of an operational SBAS, an economic benefits analysis was conducted. Accurate and reliable positioning has an expected value of $7.6 billion over 30 years for Australia and New Zealand based on tested applications. General benefits of an operational SBAS include wider coverage, enhanced accuracy, signal integrity and reduced commercial costs and infrastructure investment.

AsA should issue a disclaimer on ADSB ; “Although we made IFR aircraft fit ADSB, we don’t actually use it to provide separation. In addition, even though some VFR aircraft might have it, we don’t know where they are either, even if we do. In fact, outside radar coverage we don’t admit to knowing where anything is but we pretend that we do, sometimes. Furthermore, with the addition of new WAAS 20 year old technology, we will soon know exactly where you aren’t to an accuracy of ten centimetres”.
Thank god we didn’t let idiots like these design and construct other vital national infrastructure like our NBN, Oh! Wait!
Then all we need to do is micro-regulate as we have with ADSB, paraphrasing CAR’s: “ADSB for VFR is not mandatory but if you have it, you MUST have it switched on at all times and if it fails you are grounded after three days until it’s fixed. This is an offence of strict liability.” What a great invitation to fit new technology.
