W1ANT Pro Satellite Tracker

About this app

This Pro version has no ads and adds some features. Most notably the ability to group the satellites. The groups can then be enabled and only satellites from enabled groups will show up in the satellite overview.

Get a list of Amateur Radio satellites visible from your current location in the next 24 hours. Get an overview over their paths from acquisition to loss of signal (AOS to LOS). Only passes above the minimum elevation are shown on the list. Select one of them and get information on their on-board radios. Select one of their radios and be able to point your phone directly at it so you can easily operate it. Extra information, i.e. the actual frequencies to use for uplink and downlink is also presented taken the Doppler effect into account.

The Location view on the Satellite Overview page shows the current position of the satellite over Earth including the circle that demarcates the area where it is above 10 degrees above the horizon (reachable by radio). This view also shows its path for the next 60 minutes. Pinch to zoom and drag to change your point of view over Earth.

There is also a Passes view on the Overview page that lists all passes where this satellite will be over the horizon at the current location in the next 48 hours.

The minimum elevation for the starting list can be changed from its default 10 degrees in the Settings.

Ratings and reviews

Great app for tracking satellites - I use pretty much all of the features - satellite location, aiming, recent reports, etc. However, I also connect my IC7100 to my phone so I can send APRS packets but that causes issues. It seems the app wants to control the radio somehow; it's one of the apps which appear as recognizing the radio when I connect it. Is there an undocumented feature I'm missing? Does the app also offer either directional control or frequency control of the radio?

Love this app. I use it every morning before I get into the shack to see whether or not there will be any good passes without having to open my sat tracking software in the pc. I bought the PRO version which is worth it so that I can set up groups to exclude FM sats and sats that have not been heard. One suggestion: It would be great to be able to set an alert for sats to remind me of a pass that I'm interested in. I always seem to forget! LOL

The app is great and has allowed me as a newbie to working satellites the ability to track the satellites and make contacts. However the database seems limited and or not up to date showing every functioning amateur radio satellites. Example new cubesats Tevel 1 through Tevel 8, launched early 2022 are not shown....these and others could be very useful especially to us pro users of your app.

What's new

Added more real-time data to the UDP transmission (port 4242). Now includes azimuth, elevation both absolute and relative to device orientation.
