Keelin vs SatRadio
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Keelin
Read full descriptionHide full description
Keelin-Beacon is connected to our hardware STB1 device via Bluetooth for convenience. The STB1 is a BLE5.0de high-precision temperature sensor recorder that collects the ambient temperature of the device and uses Bluetooth broadcast to achieve 24-hour monitoring via Keelin-Beacon. 1. The current temperature value, voltage value and RSSI of nearby devices can be viewed through Bluetooth broadcast data. 2, historical data information (temperature + voltage + time, the most cocoa storage 4 days of data), at the same time can export data. Can be applied to logistics management, supply chain, warehouse, terminal and personal asset management.
SatRadio
This app provides essential tools for radio and satellite communication engineers. It includes calculators and analysis features for antenna parameters, frequency calculations, link budgets, and modem performance. It also offers miscellaneous utilities for RF engineering tasks.
- Dish antenna analysis (axial ratio, gain, line of sight)
- Frequency calculations (phase noise, doppler, wavelength)
- Radio link analysis (coaxial losses, mismatch losses, EIRP)
- Modem performance metrics (C/N, C/I, PER, BER)
- Miscellaneous RF engineering utilities (dB calculator, converters)
