Amateur satellites · your horizon
Find your next satellite pass.
29 cumulative daily page visits · Visitor map ↘
See communication satellites above your location now and their next pass within 24 hours. Your public IP gives an approximate starting location; precise coordinates give better predictions.
IP lookup uses IICSM’s existing local geolocation database. This page does not store IP lookups or send the address to an external geolocation service. VPN, mobile and satellite internet addresses may locate far from your antenna. Hosting/provider access logs may still apply.

Arrows show motion along the ground track. Length: 6 screen pixels per km/s (a 7 km/s track has a 42-pixel arrow). Direction and ground speed use the next 10 seconds of predicted motion. Near-stationary tracks below 0.05 km/s have no arrow. Arrow size stays consistent when zooming.

Visibility and communication availability
A satellite above your horizon is a potential radio path. Its repeater or transponder may be off, scheduled, in a different mode, or require equipment you do not have. Recent AMSAT reports are shown separately; “Heard” is an observation by another station, not a promise that a two-way contact is possible now. Check the AMSAT status page and the satellite’s operating schedule before transmitting.
This is a selected communication-satellite catalog, not every amateur payload. Predictions use satellite.js SGP4 and AMSAT orbital elements; elevation assumes sea-level antenna height and no terrain obstruction. Pass search samples every 30 seconds over 24 hours, so very brief passes can be missed and times/peaks are approximate. Elements older than 14 days are excluded. QO-100 can remain continuously visible within its footprint. Altitude is height above the reference Earth ellipsoid at the displayed time. Period is the mean orbital period from the current orbital elements. All times are UTC. A ham licence and appropriate station equipment are needed to transmit; internet access alone does not create a satellite radio link.

HAM RADIO SATELLITES VISITORS
Cumulative visitor map
Distinct daily visits, cumulative
Counting since 2026-09-27 (UTC). As on To the Infinity, one IP address counts once per UTC day; this is not a count of registered accounts or unique people across all time. Shared networks and automated traffic can affect totals.
Cumulative location countYour approximate current location
Your approximate current location: Columbus, US. This blue marker is shown only in your response.
Locations are approximate IP-derived city/region estimates, never GPS. Public markers require at least three cumulative daily visits. Ham Radio Satellites stores aggregate locations and short-lived keyed daily identifiers outside the public site, not raw IP addresses. Map boundaries are for orientation, not a statement of jurisdiction.
