Applanix (Trimble)
Overview
Applanix, a subsidiary of Trimble Inc., is a leading Canadian provider of advanced positioning and navigation solutions for the surveying, mapping, and geospatial industries. Headquartered in Canada, the company specializes in direct georeferencing technologies and integrated navigation systems that have become essential tools for professionals requiring precise location data across various applications including airborne surveying, mobile mapping, and autonomous systems.
Company History and Development
Applanix was founded in 1991 with a mission to develop innovative solutions combining inertial measurement units (IMUs) with Global Navigation Satellite System (GNSS) technology. The company emerged during a pivotal period in surveying and mapping when the limitations of traditional ground-based survey methods were becoming increasingly apparent, and the potential of integrating multiple positioning technologies was beginning to be recognized.
Throughout the 1990s and early 2000s, Applanix established itself as a pioneer in the direct georeferencing field. The company developed proprietary algorithms and system architectures that allowed aerial surveying and mapping professionals to eliminate the need for extensive ground control points—a revolutionary advancement that significantly reduced project timelines and costs. This innovation positioned Applanix as a critical player in the evolution of modern aerial surveying practices.
The company's growth trajectory accelerated through successive technological refinements and market expansion. Applanix became synonymous with reliability and accuracy in airborne positioning systems, earning trust from major surveying firms, government agencies, and academic institutions worldwide. This reputation for excellence and innovation led to Applanix being acquired by Trimble Inc., a globally recognized leader in positioning technologies, which further expanded the company's reach and capabilities.
Core Technologies
Direct Georeferencing
The cornerstone of Applanix's technology is direct georeferencing—a methodology that determines the precise geographic position and orientation of aerial sensors without requiring traditional ground control points. This approach fundamentally changed airborne surveying by allowing surveyors to directly assign geographic coordinates to imagery and sensor data collected during aerial missions.
Inertial Navigation Systems (INS)
Applanix integrates high-precision inertial measurement units with GNSS receivers to create robust navigation systems. These IMUs contain accelerometers and gyroscopes that measure aircraft motion in six degrees of freedom. Combined with GNSS positioning, the system maintains accurate navigation even in environments where satellite signals are temporarily unavailable, such as dense urban areas or forested regions.
Post-Processing Kinematic (PPK) and Real-Time Kinematic (RTK) Integration
The company's solutions leverage both PPK and RTK processing methodologies. PPK allows for correction of positioning data after the survey mission, enabling cost-effective solutions for projects where real-time accuracy is not essential. RTK capabilities provide real-time centimeter-level accuracy, critical for time-sensitive applications and autonomous operations.
Sensor Fusion Algorithms
Proprietary algorithms developed by Applanix intelligently fuse data from multiple sensors—including GNSS receivers, IMUs, barometric altimeters, and camera encoders—to produce optimal positioning solutions. These algorithms account for multipath effects, satellite geometry variations, and sensor drift, delivering reliable results under challenging field conditions.
Main Product Lines
POS AV Series (Airborne/Vertical)
The POS AV (Position and Orientation System for Airborne Vehicles) series represents Applanix's flagship product line for airborne applications. These systems are installed on aircraft and helicopters for aerial surveying, photogrammetry, and LiDAR operations. The POS AV directly measures aircraft position, attitude (roll, pitch, and yaw), and velocity, enabling direct georeferencing of imagery and sensor data.
Technical Specifications: - Position accuracy: 5-10 centimeters (depending on configuration) - Attitude accuracy: 0.015-0.05 degrees - Real-time and post-processing capabilities - Multi-frequency GNSS receiver integration - Integrated fiber optic or MEMS IMU options
POS LV Series (Land Vehicles)
Designed for mobile mapping applications, the POS LV (Position and Orientation System for Land Vehicles) systems mount on ground vehicles to support street-level imagery capture, mobile LiDAR, and terrestrial mapping. These systems provide continuous position and orientation data as vehicles traverse survey areas.
Technical Specifications: - Forward-facing position updates at 200 Hz - Precise vehicle trajectory determination - Integration with multiple sensor packages - GNSS/INS integration for reliable navigation in urban canyons - Support for both standard and high-grade IMU options
POS MV Series (Marine Vessels)
Applanix marine positioning systems enable hydrographic surveying, bathymetric mapping, and offshore operations. The POS MV provides accurate vessel positioning and heave motion compensation—critical factors in marine data collection where wave motion affects sensor platforms.
POS RTS Series (Real-Time Surveying)
This product line emphasizes real-time positioning and orientation for field applications requiring immediate accuracy assessment. The POS RTS integrates RTK GNSS with inertial navigation for instantaneous solution generation.
Advanced Applications
