RF Link vs CloudSatellite

RF Link brings professional-grade RF path, radio line-of-sight, Fresnel zone and path-loss analysis to your iPhone, using the Longley-Rice (ITM) irregular terrain propagation model. Built for telecom engineers, RF planners, broadcasters and wireless network designers, it delivers accurate point-to-point link evaluation for frequencies from 20 MHz to 20 GHz. Whether you are planning microwave links, Wi-Fi backhaul, LOS radio links or long-distance wireless communication, RF Link predicts terrain impact, path loss and link feasibility in seconds. KEY FEATURES ITM Longley-Rice model (20 MHz - 20 GHz) - Industry-standard Irregular Terrain Model - Accurate diffraction, scatter and line-of-sight predictions - Multiple reliability and confidence combinations Radio line-of-sight analysis - Geometric LOS check - Earth-curvature LOS with adjustable k-factor - 60% first Fresnel zone clearance - Minimum clearance at obstruction points - Suggested tower height increase Terrain elevation profiling - High-resolution elevation sampling - Plots showing terrain, curvature, LOS and Fresnel zones - Zoomable charts you can share Coverage heatmap - Signal-strength coverage area around a transmitter - Rendered over real terrain on the map Path loss and link budget - Path-loss prediction - EIRP, RSSI, SNR and link margin - Clear pass, warning and fail indicators Clean, fast interface - Map-based transmitter and receiver selection - PDF report export - Plot image sharing and saving IDEAL FOR - Wireless network planners - Microwave and LOS link engineers - UAV and drone communication designers - Amateur radio operators - Students learning RF and propagation models RF LINK PRO Every install includes a number of free calculations. RF Link Pro removes the limit, and comes two ways: - Monthly subscription: unlimited path profiles and coverage maps, billed monthly, renewing automatically. - Lifetime: a one-time purchase, no subscription. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically at the same price and period unless it is cancelled at least 24 hours before the end of the current period.

CloudSatellite brings satellite pass predictions, live tracking, antenna rotator control, radio frequency coordination and audio decoding together for satellite observers and amateur radio operators. SATELLITE LOOKUP AND PASS PREDICTIONS Find satellites by name or NORAD ID and view orbital information and amateur radio frequencies. Predict pass times, duration, azimuth and maximum elevation for your observing location. LIVE POSITIONS AND TRACKING Use the orbit map and sky view to follow satellite positions, paths and directions relative to your location. ROTATOR AND RADIO CONTROL Connect compatible antenna rotators, amateur radio transceivers or SDR devices for manual control and automatic tracking. Coordinate uplink and downlink frequencies and compensate for Doppler shift as the satellite moves. NEW: CUSTOM EPHEMERIS Import TLE and OMM JSON orbital data and manage custom ephemeris for satellite lookup, position calculations and tracking plans. NEW: SSDV AUDIO DECODING Receive live audio or process audio files to decode supported SSDV signals and reconstruct images for viewing and further processing. AUDIO AND SIGNAL TOOLS On supported devices and connections, view audio spectra and waterfall displays, record audio, and send, receive and manage SSTV images. PERSONAL SETTINGS Save favorite satellites and customize observing locations and prediction ranges. Available in Simplified Chinese, English, Japanese, Spanish, German, Brazilian Portuguese, Russian and French. Equipment control and audio features require compatible hardware and connection settings. Availability depends on the device and platform. MEMBERSHIP Monthly and annual auto-renewable subscriptions unlock all satellites in the app and custom ephemeris features. Prices are shown on the purchase screen. Payment is charged to your Apple Account after purchase confirmation. Subscriptions renew automatically unless canceled. Manage or cancel your subscription in your Apple Account subscription settings. Terms of Use / EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
