To enable screen streaming from the remote control to Android devices, the project utilizes the Solar service. Solar is a modern cloud platform designed for online streaming and unified management of devices from various manufacturers.

This functionality is available on devices running ONE firmware version 3.1 or higher.

Registration and initial setup are performed via the Solar personal account. Detailed instructions can be found at the link below.

To utilize the VPN download the OpenVPN application. This application is included in the ONE firmware versions 3.1 / 4.0, eliminating the need for a separate installation. The next step is to import the connection profile that was previously sent to you by using the import function. The next step is to import the connection profile that was previously sent to you by using the import function.

Prior to this, transfer the profile to the remote control or another Android device using a method such as Windows File Explorer.

To acquire a streaming certificate, a request can be submitted through the designated bot.

• Automatic Flight App Management: When enabled, this feature terminates conflicting flight applications to prevent connection issues (e.g., closes DJI Pilot upon launching DJI Fly).
• Background Shell Unloading: Improves application performance by closing the ONE shell interface upon launching a flight app. Note: This will disable certain background system services, such as Tweaks, during the flight session.

• External antenna/booster mode optimizes transmission power for use with an external antenna or signal booster in non-FCC regulatory environments. This mode preserves dynamic frequency switching between 2.4 GHz and 5.8 GHz bands. (Available for RC Pro, RC Pro Enterprise, and RC Plus controllers only.)

• ·Drones typically operate within legally permitted frequency and power limits, which are automatically selected based on geographical location.
• ·For example, regulatory restrictions in Russia permit only low-power transmission on the 2.4 GHz band, which is frequently subject to signal congestion.
• ·The system offers the capability to manually apply different regulatory standards:

• FCC / 5.8 / 2.4 GHz – High transmitter power + Available bands: 5.8 GHz, 2.4 GHz.
• CE / 5.8 / 2.4 GHz – Low transmitter power + Available bands: 5.8 GHz, 2.4 GHz.
• CE / 5.1–5.2 GHz (Compatibility: Mavic 3E/T/M series) – Low power, restricted band. with firmware 09.xx.
• CE / 2.4 GHz only – Low transmitter power, single band.

• System Restart Notification: When enabled, a persistent notification banner will prompt the user to restart the remote controller after switching models. (This function applies to 2nd-gen remotes).
• Persistent Radio Connection: Maintains the active link with the currently connected drone during model selection. This allows for immediate reconnection without undergoing the binding process again.
• Contextual Application Launch: Automatically initiates the corresponding flight control application (DJI Fly or DJI Pilot) upon selecting a compatible drone model.
• Alternative RTK/GNSS Routing: Activates a redundant communication path for RTK or GNSS data. This setting is recommended if the primary RTK module fails to display coordinates from the base station.
• Silent mode: Adds a dedicated software control to the interface, allowing for the immediate deactivation of all radio frequency transmission modules.

1. The requirements are established by the Federal Aviation Rules (FAR), specifically clauses 49 and 52 pertaining to unmanned aerial vehicles.
2. Drones with a maximum take-off weight of up to 30 kg may be operated without a special permit, provided all the following conditions are met.

• Outside populated areas.
• Outside airport control zones (see maps: SkyArc, FPLN, SPPI).
• More than 5 km away from uncontrolled airfields or landing areas.
• During daylight hours only.
• At a maximum altitude of 150 meters.
• The drone remains within visual line of sight (VLOS).
• No public events, sports competitions, or security events are taking place in the flight area.

1. If any of the listed conditions is not met, official permissions are required—typically from the local administration and for airspace use (AS).
2. Drones weighing up to 250 g usually do not require permission from local authorities (exceptions are listed below). For drones over 250 g, this permission is mandatory.
3. In Moscow, St. Petersburg, and Sevastopol, permission from local authorities is required for all drone operations, including for models under 250 g.
4. Permission from local authorities is also mandatory for drones under 250 g if the flight takes place in an area where public events, sports competitions, or security operations are being held.
5. To obtain permission from local authorities, liability insurance—as stipulated by Article 131 of the Civil Code (similar to motor vehicle insurance)—is required.
6. Permission for airspace use (except as outlined in point 2) requires submitting a flight plan to the relevant Air Traffic Control (ATC) center and receiving their approval.
7. Preparing a flight plan manually is a time-consuming process that requires specific expertise and usually must be initiated at least 5 days before the intended flight. This complexity is why most pilots do not obtain permission through the manual procedure.

• SkyArc — a free, non-commercial service designed to simplify the process of obtaining flight permissions: https://skyarc.ru/
• SPPI (Official Rosaviatsia service) — the official online portal of the Federal Air Transport Agency for submitting and managing flight plans.: https://sppi.ivprf.ru/

1. Create an empty file named ham_cfg_support.
2. Copy this file to the root directory of a microSD card and insert the card into the goggles unit.
3. The procedure is complete. The drone will now operate in full power mode.

• FCC mode = maximum permitted power
• CE mode = reduced regulatory power

• FCC: up to 400 mW or 640 mW, depending on the drone/controller model
• CE (used in most countries, including Europe and Russia):
• 2.4 GHz: max 100 mW
• 5.8 GHz: max 25 mW (and 5.8 GHz is often unavailable by default)

^{Visual Comparison: FCC vs CE Mode}

• Omnidirectional Antennas radiate the signal uniformly in all horizontal directions. They are ideal for general flying, providing consistent signal coverage around the pilot's location.

• Directional Antennas concentrate the signal energy into a focused beam. They are typically used with diversity receivers and are often paired with an omnidirectional or another directional antenna to ensure complete signal coverage in all flight directions.

• Linear Polarization (LP): The electromagnetic wave oscillates in a single, fixed plane (e.g., vertically or horizontally). This is the most common type, found in standard dipole antennas that are typically supplied with Video Transmitters (VTX) and Receivers (VRX), as well as in common Wi-Fi equipment.

^{Standard Dipole Antenna}

• Skew Planar Wheel
• Cloverleaf
• Helical (Spiral) antennas

^{Circular Polarization (CP) Antennas}

• The signal maintains consistent strength regardless of the drone's orientation relative to the pilot's receiving antenna. This eliminates the signal loss associated with the misalignment common in linearly polarized systems.

• CP antennas are highly effective at suppressing multipath interference, a primary source of noise in analog video transmission. This interference occurs when signal reflections from surfaces (like buildings or the ground) reach the receiver slightly delayed, interfering with the primary signal. It typically manifests as visual artifacts such as color shifts, static, image tearing, or complete signal dropouts.
