Overviw

ISTRA24 is a high-performance ultra-small ranging radar for UAV altitude determination..It adopts an original antenna design, and through ultra- efficient signal processing algorithms and high-sensitivity real-time signal processing methods based on time domain, frequency domain and phase synthesis, it can greatly reduce the physical size of the radar module and facilitate the integration of the radar module into the UAV. In the fuselage structure, new possibilities are opened up for the UAV industry. This millimeter-wave ranging radar can achieve accurate altitude measurement in the height range of 0.2 to 50m, providing great convenience for drones to maintain altitude and follow terrain.
Main application: long-endurance UAVs such as VTOL, especially landing in different places; can also be used for precise altitude maintenance and terrain following flight

Pinouts

STRA24 is factory adapted to V5+/X7 and other flight controller pin definitions; no need to modify the definition; if it is used on other flight controllers, please check the line sequence first; incorrect wiring will cause irreversible damage to the module.

Connect to flight controller

Take X7+ as an example:

NOTE: ISTRA24 can be connected to any interface of TELEM1/TELEM2/UART4.

Set flight controller parameters

Open Mission planner>Configuration>All Parameter Table; set the following parameters and save and restart

• EK2_ALT_SOURCE=1 OR EK3_RNG_USE_HGT=70
• RNGFND1_TYPE=8
