What is the OSD on the flight controller?
In the field of drones and model aircraft, flight controller is one of the core components, and OSD (On-Screen Display) is an important information display tool during flight. This article will introduce in detail the functions and functions of OSD as well as OSD-related content in recent hot topics.
1. Definition and functions of OSD
The full name of OSD is On-Screen Display, which is the screen display system. In drone flight control, the function of OSD is to superimpose flight data on the video screen in real time to facilitate the pilot to monitor the flight status. Common OSD information includes:
| Information type | Description |
|---|---|
| battery voltage | Display current battery voltage to avoid low-battery flights |
| flight altitude | Real-time display of drone height above the ground |
| flight speed | Display current horizontal or vertical speed |
| GPS signal | Indicates the number of GPS satellites and positioning status |
| airplane mode | Display the current flight control mode (such as self-stabilization, altitude stabilization, etc.) |
2. Recent hot topics and discussions related to OSD
According to the search data of the entire network in the past 10 days, the following is the hot content about OSD:
| topic | heat index | Main content |
|---|---|---|
| OSD custom settings | high | How to adjust OSD layout via Betaflight or iNav |
| Low latency OSD solution | in | Discuss the difference in OSD latency between analog and digital image transmission |
| Open source OSD firmware | in | Update and optimization of open source projects such as MWOSD |
| OSD and FPV racing | high | How racing drones optimize OSD information to reduce interference |
3. Technical implementation of OSD
The implementation of OSD usually relies on the support of flight control hardware and software. Common flight controls such as Betaflight, iNav, ArduPilot, etc. have built-in OSD functions, and users can adjust the display content through configuration tools. The following is the OSD support of mainstream flight controllers:
| flight control system | OSD support | Features |
|---|---|---|
| Betaflight | Yes | Supports high degree of customization, suitable for FPV flight |
| iNav | Yes | Support GPS navigation information display |
| ArduPilot | Yes | Suitable for professional aerial photography and autonomous driving |
4. How to choose a suitable OSD solution
The following factors need to be considered when choosing an OSD solution:
1.flight use: FPV racing requires a simple OSD, while aerial photography may require more data.
2.Hardware compatibility: Make sure the flight control and video transmission support the OSD overlay function.
3.Software support: Open source firmware (such as MWOSD) or commercial solutions (such as DJI OSD).
5. Summary
OSD is an indispensable tool for drone flight, which can help pilots grasp the flight status in real time. With the development of technology, the functions and customization capabilities of OSD are also constantly improving. Recent hot topics show that users have high demand for OSD latency optimization and personalized settings, and more innovative solutions may appear in the future.
