Types of GPS Module for Drone

Several types of GPS modules for drones are available on the market, each with its own set of features and capabilities. Here are some common types:

• Standard GPS Module:

  Standard GPS modules are the most basic GPS modules. They are less expensive and provide only basic GPS functionality. They are suitable for applications that do not require high precision or reliability, such as hobbyist drones or low-cost commercial drones. However, standard GPS modules may have limitations in terms of accuracy, altitude, and speed.

• RTK GPS Module:

  RTK (Real-Time Kinematic) GPS modules are designed for high-precision positioning. They use a network of base stations to provide real-time corrections to the GPS signals received by the drone. RTK GPS modules can achieve centimeter-level accuracy, making them ideal for applications that require precise positioning, such as surveying, agriculture, and construction. However, RTK GPS modules are more expensive and require a base station or a connection to a base station network.

• GNSS (Global Navigation Satellite System) Module:

  GNSS modules are GPS modules that use multiple global navigation satellite systems, including GPS, GLONASS, Galileo, and BeiDou. By using signals from more satellites, GNSS modules improve positioning accuracy and reliability, especially in challenging environments like urban areas or dense forests. GNSS modules are suitable for various drone applications, including mapping, inspection, and delivery, where reliable positioning is critical.

• Dual-Band or Triple-Band GPS Module:

  Dual-band or triple-band GPS modules operate on multiple frequency bands, such as L1, L2, and L5. This allows them to receive more satellite signals and improve positioning accuracy and robustness. Dual-band or triple-band GPS modules are particularly beneficial in applications with demanding positioning requirements or in environments with signal interference. They are often used in professional drones for mapping, monitoring, and other critical missions.

• Integrated Flight Controller with GPS:

  Some flight controllers come with built-in GPS modules. These integrated systems simplify the drone's hardware and provide basic GPS functionality for stabilization, waypoints, and return-to-home features. Integrated GPS modules are suitable for entry-level or hobbyist drones, offering convenience and cost savings while enabling basic GPS features.

Specifications and Maintenance of GPS Module For Drone

• Regular Cleaning

  For the drone's GPS module to function properly, it must be cleaned regularly. Dust and moisture may interfere with the module's performance. Use a microfiber cloth that is soft and dry to clean the GPS module and surrounding areas. Take extra care not to scratch the drone's surface or damage any electrical components. Before cleaning, ensure the drone is turned off and unplugged. Make sure the cleaning supplies are dry and free of moisture so that no water gets inside the drone.

• Software Updates

  Regularly check for software updates from the drone manufacturer. Install these updates using the instructions provided. The updates may include improvements to the GPS module's performance, bug fixes, or new features. The updates ensure that the GPS module functions optimally and remains compatible with the rest of the drone's system. Follow the manufacturer's instructions for updating the software safely.

• Check GPS Signal Strength

  Before each flight, use the drone's interface to check the GPS signal strength. A strong signal is essential for accurate positioning. If the signal is weak, inspect the GPS module and its antenna for any physical damage. Ensure that the module and antenna are clean and free from obstacles that may block the signal. Environmental factors like tall buildings or dense trees can also affect the signal strength. Choose a location with fewer obstructions to improve the GPS performance.

• Calibration

  Occasionally, the drone may require calibration to ensure the GPS module provides accurate data. Follow the manufacturer's instructions for calibrating the drone's compass and GPS system. This is usually done by performing a series of turns in different directions while the drone is in the air. The calibration process aligns the GPS module with the drone's flight controls, improving location accuracy. In case of any discrepancies in the GPS data or when flying in a new location, calibration is necessary.

• Avoid Extreme Conditions

  Avoid exposing the drone's GPS module to extreme temperatures, humidity, or physical stress. Extreme conditions can damage the module and affect its performance. For instance, flying the drone in very cold weather may cause the GPS module to respond slowly. Similarly, high temperatures can lead to overheating and shorten the module's lifespan. Also, protect the GPS module from mechanical shocks or vibrations that could occur during rough landings.

• Battery Maintenance

  For optimal performance of the GPS module, maintain the drone's battery properly. Ensure the battery is charged sufficiently before each flight. A low battery can lead to unstable power supply, affecting the GPS module's operation. Follow the manufacturer's instructions for charging, discharging, and storing the battery safely. Avoid overcharging or fully depleting the battery, as this can shorten its lifespan.

How to choose GPS modules for drones

There are several factors that business buyers need to put into consideration when selecting a GPS module for drone. The most important one is understanding the needs of their target customers. If customers need GPS for commercial drones, they will be looking for accurate positioning, reliability, and real-time data to carry out their mapping and surveying tasks. In this case, stock drones with high-end GPS modules that have RTK capabilities.

For customers who use drones for recreational purposes, it’s enough to have a basic GPS module that offers location tracking and waypoint navigation. Select a wider variety of modules to cater to different customers' budgets and needs. Consider the environmental conditions and the operating environment of the drones. Businesses that use drones for agricultural purposes will fly the drones over vast fields. In such an instance, the drones need a long-range GPS module with a robust communication system to ensure constant GPS tracking and data across the field.

Check the ease of integration and compatibility of the GPS module with the drone's existing systems. A GPS module that is compatible with various drones and is easy to integrate will be in high demand. Consider the size and form factor of the GPS module. Smaller and lightweight modules are ideal for consumer drones, while larger ones can be used in industrial drones. Finally, stock dual-band and multi-band GPS modules. They will provide buyers with better accuracy and reliability.

How to DIY and Replace GPS Module For Drone

Replacing the GPS module on a drone is a technical process, however, it can be done by following the right steps. First, it is important to have the right tools and a new GPS module that is compatible with the drone.

Here are the tools that are required:

• New GPS module
• Screwdriver set
• Needle-nose pliers
• Small plastic pry tool
• Electrostatic discharge (ESD) strap (optional)

Below are the steps:

• Turn off the drone and unplug the battery. This will ensure the process is safe and the drone is not powered.
• Use a screwdriver to remove the screws holding the drone's cover and carefully lift it off.
• Locate the old GPS module on the drone. It is usually near the front or center of the drone, and it may be connected to the circuit board with a few screws and a ribbon cable.
• Use pliers or a pry tool to carefully disconnect the old GPS module from the circuit board. Be careful not to damage the surrounding components or the circuit board itself.
• Take the new GPS module out of its packaging and ground it to the circuit board. This will help prevent electrostatic discharge (ESD) that can damage electronic components.
• Connect the new GPS module to the circuit board using the ribbon cable and any screws that were removed in step 4. Make sure the connections are secure and the module is properly mounted.
• Reattach the drone's cover and secure it with the screws removed in step 2. Make sure the seals are tight and the drone's integrity is maintained.
• Plug in the drone's battery and power it on. Check that the new GPS module is functioning correctly and that the drone is receiving GPS signals.
