SatFinder vs Quick Quake

With SatFinder you can adjust your satellite antenna in a few seconds and with 4 simple steps: STEP 1 - CHOOSE YOUR ANTENNA Choose one of the four different antenna designs: - Offset antennas (the most common, is slightly oval, the LNB is not in the center). - Special design (e.g. Oblong shaped Offset antenna, Multifeed antenna) - Parabolic antenna (LNB is located in the center of the reflector, usually larger than 100cm) - Flat or planar antenna (small, camping antennas) If you have an offset antenna, enter the height and width of the antenna. If your antenna has a special shape, enter the offset angle and the size of the satellite antenna. You can find the offset angle in the manual of your satellite antenna. For parabolic antennas it is sufficient to enter the antenna diameter. With a flat antenna you do not have to set anything. If you know the exact antenna name, check if your antenna is already in the database. Tip: Press the wizard button to measure the size of the satellite antenna using the iPhone camera and LiDAR scanner. STEP 2 - CHOOSE YOUR SATELLITE To quickly and easily select a suitable satellite, simply press the "AUTO" button. The SatFinder will now automatically search for satellites that are in your reception area and that offer TV or radio stations in your language (the language setting of your iPhone will be selected). The stars (1-10) shown in the table result from the number of radio and TV channels offered and the reception strength at your location. If you want to receive a special satellite, switch off "AUTO": Now you can simply scroll through the table and select the satellite. Faster is the search function - just enter the name of the satellite, the channel or the orbit position. You can also reduce the number of table entries by hiding satellites that are not available at your location or do not broadcast in your language. With the button "Channel Info" you can check which channels the selected satellite is currently broadcasting - including all channel parameters for your satellite receiver. STEP 3 - CHECK OBSTACLES For a smooth satellite reception, there must not be any obstacles between the satellite and your satellite antenna. You can check this with the "View" function. Simply aim at the satellite and watch the signs (GREEN - no obstacle, RED - caution, free view may not be given). Tip: Press the button for the assistant to activate the voice output. STEP 4 - ADJUST ANTENNA In the menu item "Align" different graphics appear depending on the selected antenna type. If you use an offset antenna, you have to adjust the azimuth and elevation separately. With planar or parabolic antennas the adjustment of the angles is done together. Before you press the "Start" button, a video clip shows how to position your iPhone at the antenna. Tip: Press the button for the assistant to activate the voice output. STEP 5 - FINE TUNING If necessary, you can optimize the reception of your satellite system. The SatFinder provides you with the function "FineTuning". To use this function, you need a second iOS device. One device serves as a camera; the second device as a monitor. Simply place an iPhone in front of your reception screen and observe changes in picture quality while slightly rotating or tilting your satellite antenna. With the FineTuning feature, you'll have visual contact with your TV even when you're out of sight. THAT'S IT. YOU SHOULD NOW BE ABLE TO ENJOY INTERFERENCE-FREE SATELLITE RECEPTION... Note: Satellite antenna tuning is only available on iOS devices with LiDAR sensor (e.g. iPhone 12 Pro).

Rapid earthquake location and magnitude verification has never been easier. Quick Quake is also a great educational tool – simply use the demo data to see how P (primary) and S (secondary) waves are used to determine the location of an earthquake. Quick Quake is an earthquake data analysis tool that allows users to quickly determine the epicentre and magnitude of an earthquake by simply picking a P wave and S wave arrival from a single seismograph, then moving the epicentre around a map until the seismograms from the other stations line up in time. The Seismology Research Centre has developed Quick Quake so that users of the Quake Server seismic observatory data management system can quickly verify the automatic event notifications that Quake Server sends out by email. The traditional method of locating earthquakes can take anywhere from 10-20 minutes, but with Quick Quake you can verify or refine the automatic eqServer location and magnitude in less than a minute. How to use Quick Quake with the demo data: • Select which station you wish to use to pick a P and S wave (the “key site”) and hit the target icon • Drag the P (primary wave) marker to the right until it aligns with the first signal that you can see above the background noise • Drag the S (secondary wave) marker to the left until it aligns with the significant increase in signal level (see the screenshots as a guide) • Pinch to zoom the time and amplitude scale if you need better resolution • Continue to the locating screen, where you can drag the target around the circle until the waveforms on the left of the screen roughly align with the P and S travel time guide lines It’s that simple. The solution should work no matter which station you choose, but the closer the station the easier the P and S wave arrival times will be to pick. If you have an Quake Server, just log in using your credentials and the server's IP address or domain name, then you can browse through recent (and past) automatic events and proceed as above. On the “Select a Key Site” screen, you can defer stations from your calculations using a left-swipe, or restore them with a right-swipe. You can also sort your stations in order of distance from the selected “key site”. On the “Locate Event” screen there is are options to adjust the P-wave and S-wave travel velocities to suit your local conditions, as well as the depth of the earthquake. The iPad version shows quick-adjustment buttons, and iPhone and iPad versions include three presets for P and S velocity “models” - now with a customisable magnitude formula.
