The Tello drone, a collaboration between DJI and Ryze Robotics, has been making waves in the drone enthusiast community with its impressive features and affordable price tag. One of the most frequently asked questions about this drone is whether it has GPS capabilities. In this article, we will delve into the world of drone navigation and explore the Tello drone’s GPS capabilities in detail.
Understanding Drone Navigation Systems
Before we dive into the specifics of the Tello drone’s GPS capabilities, it’s essential to understand the basics of drone navigation systems. Drones use a combination of sensors and navigation systems to stabilize and control their flight. The primary navigation systems used in drones are:
Types of Drone Navigation Systems
- GPS (Global Positioning System): A network of satellites orbiting the Earth that provide location information to GPS receivers on the ground. GPS is widely used in drones for navigation, tracking, and stabilization.
- GLONASS (Global Navigation Satellite System): A Russian satellite navigation system that provides location information to GLONASS receivers.
- BeiDou (BDS): A Chinese satellite navigation system that provides location information to BDS receivers.
- Inertial Measurement Unit (IMU): A sensor that measures the drone’s acceleration, roll, pitch, and yaw.
- Barometer: A sensor that measures the drone’s altitude.
The Tello Drone’s Navigation System
The Tello drone uses a combination of sensors and navigation systems to stabilize and control its flight. The drone is equipped with:
Tello Drone’s Sensors and Navigation Systems
- Vision Positioning System (VPS): A system that uses cameras and sensors to detect the drone’s surroundings and stabilize its flight.
- IMU: Measures the drone’s acceleration, roll, pitch, and yaw.
- Barometer: Measures the drone’s altitude.
However, the Tello drone does not have a built-in GPS module. Instead, it relies on its VPS and IMU to navigate and stabilize its flight.
How Does the Tello Drone Navigate Without GPS?
The Tello drone’s VPS uses a combination of cameras and sensors to detect the drone’s surroundings and stabilize its flight. The system works by:

Does the Tello Drone Have GPS?
The Tello drone does not have a built-in GPS system. Instead, it relies on its vision positioning system (VPS) to navigate and maintain its position. The VPS uses a camera to detect the ground and surrounding environment, allowing the drone to estimate its altitude and position.
While the lack of GPS may seem like a limitation, the Tello drone’s VPS is surprisingly effective. It allows the drone to hover in place and maintain its position, even in the absence of GPS signals. However, it’s worth noting that the VPS may not be as accurate as GPS in certain situations, such as high-altitude flights or flights in areas with limited visual features.
How Does the Tello Drone’s VPS Work?
The Tello drone’s VPS uses a combination of computer vision and sensor data to estimate its position and altitude. The camera captures images of the ground and surrounding environment, which are then processed using sophisticated algorithms to detect features and patterns. This information is combined with data from the drone’s sensors, such as its accelerometer and gyroscope, to estimate its position and orientation.
The VPS is a complex system that requires significant processing power and sophisticated software. However, it allows the Tello drone to navigate and maintain its position in a wide range of environments, from indoor spaces to outdoor areas with limited GPS coverage. While it may not be as accurate as GPS in certain situations, the VPS is a powerful tool that enables the Tello drone to fly and navigate with ease.
Can I Use the Tello Drone Outdoors?
Yes, you can use the Tello drone outdoors, but its performance may be affected by the lack of GPS. In areas with limited visual features, such as open fields or deserts, the drone’s VPS may struggle to maintain its position and altitude. However, in areas with more visual features, such as trees, buildings, or hills, the VPS can provide accurate and reliable navigation.
It’s also worth noting that the Tello drone is not designed for long-range flights or high-altitude operations. It’s best suited for short-range flights in areas with limited obstacles and visual features. If you plan to use the Tello drone outdoors, make sure to follow all safety guidelines and regulations, and always keep the drone in sight.
How Accurate is the Tello Drone’s VPS?
The accuracy of the Tello drone’s VPS depends on various factors, such as the environment, lighting conditions, and the drone’s altitude. In general, the VPS is most accurate in areas with rich visual features, such as indoor spaces or outdoor areas with trees, buildings, or hills. However, in areas with limited visual features, such as open fields or deserts, the VPS may struggle to maintain its position and altitude.
In terms of numerical accuracy, the Tello drone’s VPS can maintain its position within a few meters of its actual location. However, this accuracy can vary depending on the specific environment and conditions. It’s also worth noting that the VPS is not as accurate as GPS in certain situations, such as high-altitude flights or flights in areas with limited GPS coverage.
Can I Upgrade the Tello Drone’s Navigation System?
No, you cannot upgrade the Tello drone’s navigation system to include GPS. The drone’s VPS is a built-in system that is integrated into its hardware and software. While you can modify the drone’s software or add external sensors, you cannot replace the VPS with a GPS system.
However, you can use external accessories or software to enhance the Tello drone’s navigation capabilities. For example, you can use a smartphone app to provide GPS data to the drone, or add external sensors to improve its stability and control. However, these modifications may require significant technical expertise and may void the drone’s warranty.
How Does the Tello Drone’s VPS Compare to GPS?
The Tello drone’s VPS is a different navigation system than GPS, with its own strengths and limitations. While GPS provides accurate and reliable navigation in a wide range of environments, the VPS is more suited for short-range flights in areas with rich visual features. In terms of accuracy, GPS is generally more accurate than the VPS, especially in areas with limited visual features.
However, the VPS has its own advantages, such as its ability to navigate in areas with limited GPS coverage, such as indoors or in urban canyons. The VPS is also more resistant to GPS interference and spoofing, which can be a significant advantage in certain situations. Overall, the VPS and GPS are complementary navigation systems that can be used in different contexts and applications.
What Are the Limitations of the Tello Drone’s VPS?
The Tello drone’s VPS has several limitations, including its reliance on visual features and its limited range and accuracy. In areas with limited visual features, such as open fields or deserts, the VPS may struggle to maintain its position and altitude. The VPS is also limited by its range, which is typically around 10-20 meters.
Additionally, the VPS can be affected by lighting conditions, such as bright sunlight or low light, which can reduce its accuracy and reliability. The VPS can also be affected by obstacles, such as trees or buildings, which can block its view of the ground and surrounding environment. Overall, the VPS is a powerful navigation system, but it has its own limitations and challenges.
