Combining SBG Systems’ inertial systems with LiDAR for drone mapping enhances accuracy and reliability in capturing precise geospatial data.

Here’s how the integration works and how it benefits drone-based mapping:

• A remote sensing method that uses laser pulses to measure distances to the Earth’s surface, creating a detailed 3D map of the terrain or structures.
• SBG Systems’ INS combines an Inertial Measurement Unit (IMU) with GNSS data to provide accurate positioning, orientation (pitch, roll, yaw), and velocity, even in GNSS-denied environments.

SBG’s inertial system is synchronized with the LiDAR data. The INS accurately tracks the drone’s position and orientation, while the LiDAR captures the terrain or object details below.

By knowing the precise orientation of the drone, the LiDAR data can be accurately positioned in 3D space.

The GNSS component provides global positioning, while the IMU offers real-time orientation and movement data. The combination ensures that even when the GNSS signal is weak or unavailable (e.g., near tall buildings or dense forests), the INS can continue to track the drone’s path and position, allowing for consistent LiDAR mapping.

Jamming and spoofing are two types of interference that can significantly affect the reliability and accuracy of satellite-based navigation systems like GNSS.

Jamming refers to the intentional disruption of satellite signals by broadcasting interfering signals on the same frequencies used by GNSS systems. This interference can overwhelm or drown out the legitimate satellite signals, rendering GNSS receivers unable to process the information accurately. Jamming is commonly used in military operations to disrupt the navigation capabilities of adversaries, and it can also affect civilian systems, leading to navigation failures and operational challenges.

Spoofing, on the other hand, involves the transmission of counterfeit signals that mimic genuine GNSS signals. These deceptive signals can mislead GNSS receivers into calculating incorrect positions or times. Spoofing can be used to misdirect or misinform navigation systems, potentially causing vehicles or aircraft to veer off course or providing false location data. Unlike jamming, which merely obstructs signal reception, spoofing actively deceives the receiver by presenting false information as legitimate.

Both jamming and spoofing pose significant threats to the integrity of GNSS-dependent systems, necessitating advanced countermeasures and resilient navigation technologies to ensure reliable operation in contested or challenging environments.

A payload refers to any equipment, device, or material that a vehicle (drone, vessel …) carries to perform its intended purpose beyond the basic functions. The payload is separate from the components required for the vehicle operation, such as its motors, battery, and frame.

Examples of Payloads:

• Cameras: high-resolution cameras, thermal imaging cameras…
• Sensors: LiDAR, hyperspectral sensors, chemical sensors…
• Communication equipment: radios, signal repeaters…
• Scientific instruments: weather sensors, air samplers…
• Other specialized equipment

GNSS stands for Global Navigation Satellite System and GPS for Global Positioning System. These terms are often used interchangeably, but they refer to different concepts within satellite-based navigation systems.

GNSS is a collective term for all satellite navigation systems, while GPS refers specifically to the U.S. system. It includes multiple systems that provide more comprehensive global coverage, while GPS is just one of those systems.

You get improved accuracy and reliability with GNSS, by integrating data from multiple systems, whereas GPS alone might have limitations depending on satellite availability and environmental conditions.

GNSS represents the broader category of satellite navigation systems, including GPS and other systems, while GPS is a specific GNSS developed by the United States.
