What is altitude hold in drones?

Altitude hold is a crucial feature in modern drones that allows them to maintain a consistent altitude during flight. It offers numerous advantages and enhances the overall flight experience for both recreational and professional drone pilots. In this comprehensive guide, we will delve into the concept of altitude hold, explore how it works, discuss its benefits, and highlight its applications in various drone operations.

Understanding Altitude Hold:

Altitude hold is a flight mode in drones that automatically adjusts the throttle or motor power to maintain a steady altitude without constant manual input. It relies on sensors, such as barometers or altimeters, to measure the drone’s altitude relative to the ground or sea level.

How Altitude Hold Works:

  1. Sensor Measurement: Onboard sensors measure atmospheric pressure or altitude using barometric or altimetry sensors.
  2. Reference Point Establishment: The sensor readings are used as a reference point when the drone is at the desired altitude.
  3. Automatic Adjustments: As the drone ascends or descends, the altitude hold system continuously compares the current altitude with the reference point. It automatically adjusts the motor power or throttle to maintain a steady altitude.

Benefits of Altitude Hold:

  1. Stable Flight: Altitude hold ensures a stable flight experience, allowing pilots to focus on other tasks such as camera operation, aerial photography, or data collection without worrying about altitude variations.
  2. Precise Aerial Photography and Videography: With altitude hold, drone pilots can capture smooth and stable aerial shots, enabling precise framing, smooth panning, and seamless video recording. This feature is particularly beneficial for professional photographers, cinematographers, and content creators.
  3. Flight Training and Learning: Altitude hold is an excellent feature for beginners learning to fly drones. It reduces the risk of crashes caused by altitude fluctuations, providing a more controlled and manageable flight experience.
  4. Energy Efficiency: By automatically adjusting the motor power or throttle to maintain a constant altitude, altitude hold reduces power consumption. This results in improved energy efficiency and longer flight times.

Applications of Altitude Hold:

  1. Aerial Photography and Videography: Altitude hold plays a vital role in capturing high-quality aerial images and videos for various applications, including real estate photography, film production, and environmental monitoring.
  2. Surveying and Mapping: Altitude hold facilitates precise mapping and surveying operations, allowing drones to fly at a consistent altitude while capturing accurate data for terrain modeling, 3D mapping, and infrastructure surveys.
  3. Inspection and Monitoring: Altitude hold assists in conducting inspections of infrastructure, including power lines, bridges, and buildings. Drones equipped with specialized sensors can fly at a constant altitude, capturing detailed visual data for analysis and monitoring purposes.
  4. Search and Rescue Operations: Altitude hold is particularly valuable in search and rescue missions. It enables drones to maintain a steady altitude while performing aerial searches, optimizing their effectiveness in locating missing persons or providing situational awareness.


Altitude hold is a fundamental feature in modern drones that provides stability, precision, and convenience during flight. Its ability to automatically maintain a consistent altitude enhances aerial photography, videography, flight training, and various professional applications. Whether you’re an enthusiast or a professional pilot, understanding the functionality and benefits of altitude hold is crucial for maximizing your drone’s capabilities and capturing stunning aerial footage or performing critical operations with ease.
