Description
Description:
- KrakenSDR is a Software-Defined, Coherently Operated, Five-RX-Channel Radio.
A coherent radio allows for very interesting applications, such as radio direction finding, passive radar, and beamforming. Some use cases include:
- Physically locating an unknown transmitter of interest (e.g. illegal or interfering broadcasts, noise transmissions, or just as a curiosity)
- HAM radio experiments such as radio fox hunts or monitoring repeater abuse
- Tracking assets, wildlife, or domestic animals outside of network coverage through the use of low power beacons
- Locating emergency beacons for search-and-rescue teams
- Locating lost ships via VHF radio
- Passive radar detection of aircraft, boats, and drones
- Traffic-density monitoring via passive radar
- Beamforming
- Interferometry for radio astronomy
Improvements:
- Automatic calibration hardware. It is no longer necessary to manually disconnect antennas during calibration. It all happens automatically when you change frequency. This will allow for KrakenSDR stations to be remotely operated.
- Five channels. KrakenSDR has five channels instead of four, which greatly improves-direction finding accuracy.
- Low-noise design. KrakenSDR has a cleaner spectrum with much less internal noise than KerberosSDR.
- USB Type-C ports and rugged, CNC-milled enclosure. KrakenSDR is built for high reliability in the field.
- Interface with external devices. Bias tees on all ports allow for LNAs and other devices to be powered easily.
- Improved DAQ, DSP, and GUI software. Built on the foundation of the KerberosSDR software, the KrakenSDR software adds auto-calibration, tracking of intermittent signals, greater stability, arbitrary processing-block sizes, and a new web-based GUI.
- Software upgrades. Improvements to existing companion software and plans for new companion software.
- Custom App for Android. Custom App can automatically determine the location of a transmitter and provide automatic turn-by-turn navigation to the transmitter location.
Features & Specifications of KrakenSDR:
- Five-channel, all clocked to a single local oscillator
- Built-in automatic coherence synchronization hardware
- Automatic coherence synchronization and management via provided Linux software
- 24 MHz to 1766 MHz tuning Range (standard R820T2 range, and possibly higher with hacked drivers)
- 4.5 V bias tee on each port
- Core DAQ and DSP software is open source and designed to run on the board for Raspberry Pi 4 (see links below)
- Direction-finding software for Android (free for non-commercial use)
Package Included:
- 1 x SDR Receiver
