The _ISS Detector_ Android application, with over 5 million downloads, offers precise predictions for visible passes of the International Space Station. It notifies users minutes before an overhead pass, integrating local weather conditions to ensure optimal viewing opportunities. The core functionality focuses on the ISS, but in-app purchases extend its capabilities to track other celestial and artificial objects. Optional extensions, available via in-app purchase, allow users to monitor dozens of amateur radio and weather satellites, providing real-time transmitter information and Doppler frequencies. Additional extensions cover _Starlink_ satellites, the _Hubble Space Telescope_, rocket stages, bright satellites, comets, and planets, expanding the scope beyond the ISS to a broader range of observable space phenomena. The app's interface is designed for ease of use, displaying pass times, directions, and elevation. It adapts predictions based on the user's GPS location, ensuring accurate local forecasts. The latest update, dated April 3, 2026, includes corrections for magnitude values and various speed and stability optimizations.

The CES Wireless Technologies website details a range of **GPS fleet tracking** solutions designed for mobile information systems. It highlights offerings such as dispatch and mapping software, Automatic Vehicle Location (AVL) systems, and mobile data display terminals. The platform also mentions support for Automatic Number Identification (ANI) and Continuous Tone-Coded Squelch System (CTCSS) functionalities, indicating integration with two-way radio communication protocols. Specific products include GPS tracking devices and associated software for fleet management, emphasizing features like real-time location monitoring and operational efficiency. The site positions itself as a manufacturer in this specialized domain, catering to commercial and public safety sectors requiring robust mobile data solutions. While the page title mentions "Ham Radio Directory" categories, the content primarily focuses on commercial GPS and fleet management technologies, not amateur radio applications. The listed products are geared towards professional mobile radio (PMR) environments rather than typical ham radio operations.

Display your current Maidenhead locator with 10 digit precision. It also computes bearing and distance to a set of target locations using locator or latitude / longitude. Useful to align antennas in VHF / UHF / microwave DX activities. No network or fancy maps usage, so it can be used even in remote locations.

Amateur Packet Reporting System (APRS) operations often require compact, reliable solutions for transmitting position data, particularly for mobile or portable stations. This resource details the construction of the _Tiny Track-I_, a transmit-only APRS tracker designed for straightforward integration with a VHF radio and a Global Positioning System (GPS) receiver. It enables hams to broadcast their location without the complexity of a full-duplex TNC. The project outlines the printed circuit board (PCB) layout and schematic, based on an original design by N6BG, with a personal PCB drawing by SV1BSX. It includes specific component placement and notes an additional 10uF/10V capacitor (C5) for improved IC voltage decoupling, a modification not present in the original N6BG diagram. The unit connects to a computer or GPS via a DB9 female connector. This tracker is ideal for basic position reporting, offering a simple and effective way to participate in APRS networks. Its small footprint makes it suitable for vehicle installations or field deployments where space is limited, providing a **reliable 9600 baud** data stream for location updates.

ToyNTP is a simple freeware time server for Windows that implements the SNTP protocol and uses a GPS receiver, Garmin GPS 18x LVC, as time reference. ToyNTP was designed to be used with Faros in the locations where access to the SNTP servers on the Internet is not available, but it may be used for other purposes as well, in particular, it may be configured to keep the PC clock synchronized to a GPS receiver.

The short-term aurora forecast, based on the OVATION model, predicts aurora location and intensity 30 to 90 minutes ahead, aligning with solar wind travel time. Maps show aurora ovals in green, turning red for higher intensity. Aurora, visible after sunset or before sunrise, impacts technologies like radio communication, GPS, and power grids. It's a mesmerizing space weather spectacle, drawing travelers to the Arctic.

This study analyzes the antenna pattern of the Utah Amateur Radio Club's 146.760 MHz repeater following antenna relocation in 1997. Noting degraded transmission toward the north, a customized signal mapping system using a Yaesu FT-817, GPS, and software was developed to log real-time signal data. Calibration techniques extended the radio's signal range, enabling precise field measurements. The method allowed continuous signal strength monitoring while driving, revealing anomalies in coverage likely due to tower modifications. Findings helped assess and visualize the antenna’s actual radiation pattern and highlighted environmental impact on signal distribution.

Meshtastic utilizes _LoRa_ radio protocol for long-range, off-grid communication, functioning as a decentralized mesh network. The system allows users to send and receive text messages without reliance on existing infrastructure or a phone for mesh communication, leveraging inexpensive LoRa radios. Key features include encrypted communication, excellent battery life, and optional GPS-based location services, with radios designed to rebroadcast messages to ensure all group members receive them. The project has achieved a record range of **331km** and is 100% community-driven and open source, with its codebase available on GitHub. Unlike traditional ham radio, Meshtastic operates on LoRa, which is generally accessible without additional licenses. Each Meshtastic radio can be paired with one phone at a time for message exchange, and support is entirely volunteer-based.
