One of the reasons we use R2Sonic sonars for asset inspection is because of its TruePix sidescan output. This excellent article explains why/how it is different to Snippets backscatter. Snippets vs TruePix™, how do they compare? – R2Sonic:
Great Barrier Reef: Scientists find reef taller than Empire State Building – BBC News: More great work by Dr Robin Beaman and the survey team on Schmidt Ocean’s Falkor.
Kongsberg are launching “MultiFrequency mode” and there is a webinar tomorrow to sign up to https://www.kongsberg.com/maritime/about-us/news-and-media/blog-stories/webinar-em-multifrequency/ Similar to R2Sonic’s multispectral mode maybe?
ASV Harry has just completed his acceptance trials and there were a number of tests that we performed which are unique to ASVs, which I thought I would share. Wifi Link Test The SeaRobotics ASV is autonomous but it is always good to see what is going on and how do you communicate nowadays – […]
Today is the first day for 4D Ocean which I set up to provide autonomous survey solutions to the seabed mapping community! The technology is now there to be able to do fully autonomous surveys but it is still early days and requires a great deal of investment in how to do it and the […]
I’ve been helping out a potential client with extracting data from the water column packets of an @TeledyneRESON multibeam system in 1500m of water. It was only when I extracted it (using the new awesome water column tools in @QPSQimera) that I realised how big they were. One is 750m high and the other is […]
This is pretty amazing to see. An entire bay has become dry following the 7.8 magnitude earthquake off New Zealand last week. A bay on the Kaikōura coast has moved up 1.5 m and therefore is now pretty dry. Photos by Casey Milne (pre) and Andrew Spencer (post)
I’ve been taking different AUV datasets through Qimera and I must say, it is really easy. It is even easier now that as well as the post processed inertial SBET format, I have been beta testing the Kongsberg Navlab post processed position and pressure formats too. It only took a minute to get all the […]
This fantastic story map provides a history of the development of water column processing from research to reality. It was put together by Moe Doucet (@metamoe) from QPS and Victoria Price from Normandeau Associates. They presented it at @ESRIOceans this week. Well worth a view.
R2Sonic have just released a new firmware update that allows the system to ping in succession at different frequencies. It works best on the Sonic 2026 as this can ping at 100 kHz, 200 kHz and 400 kHz. QPS QINSy records the frequency with each ping and then FMGT (the backscatter app) processes each frequency […]
