PortablePlanner is a Satellite Frequency Calculator designed for portable satellite communication operations. Based on the crawled page content, it lets users calculate satellite signal frequencies from their current location and satellite orbital parameters, and displays TX Frequency, RX Frequency, Satellite Status, and calculation time in the interface. Overall, it feels more like a vertical tool for a specific use case than a general-purpose development framework or platform.
The tool offers “Select Satellite” for choosing a satellite, “Frequency Type” for distinguishing TX/RX, and supports MHz frequency input. A ±3kHz Fine Tuning slider allows fine frequency adjustment, which is useful in satellite communications for handling real-time requirements such as Doppler shift correction. For location, it supports “Get My Location” and Grid Square input. When Partner Mode is enabled, users can enter a partner station’s Grid Square; the on-screen description indicates that the entered frequency will be treated as the partner station’s frequency, with TX/RX updating in real time. It also includes TLE Data Refresh, Force Download, Keep Screen On, and Update Available, suggesting that it accounts for continuous field operation and orbital data updates.
The crawled content does not provide pricing, payment methods, company information, an open-source license, self-hosting options, or any API/SDK, third-party integrations, or ecosystem details. As a result, its business model and extensibility for secondary development cannot be assessed. In terms of documentation, only interface text is currently visible; there are no tutorials, explanations of calculation formulas, supported satellite lists, frequency range details, or troubleshooting materials. Documentation completeness is therefore unclear.
Its main strength is a very clear use case: quickly calculating TX/RX frequencies for portable satellite communication, with support for current location, grid-based positioning, partner station mode, and TLE refresh. It is strongly oriented toward practical operation. The downside is that little public information is available: there is no clear explanation of accuracy, data sources, offline capability, supported platforms, account system, or technical support. For developers, there is also no visible callable API or integration capability.
It is best suited to amateur radio satellite communication enthusiasts, portable field operators, and users who need to quickly convert satellite uplink/downlink frequencies. It is less suitable for teams looking for a general developer tool, automation API, or self-hostable system. Access from mainland China cannot be determined from the available content and should be considered unknown; payment methods are also not disclosed. If access or data refresh is restricted, users may need to prepare a local alternative calculator or other satellite tracking/frequency planning software as a backup.
