Leica Geosystems has been a pioneer in integrating direct IMU georeferencing systems into airborne sensors and was first to market with a commercial, large-format digital sensor (camera) system. The GNSS/IMU system is an integral part of the Leica ADS80 airborne digital sensor as well as the Leica ALS60 airborne LIDAR system. Leica Geosystems has gained many years of practical experience in this field allowing it to closely study the applications and development of this technology. The resulting Leica Inertial Position & Attitude System (IPAS) was first embedded in the airborne systems Leica ADS40 and Leica ALS50 and have become standard for all product lines. Additional market requests have now led Leica Geosystems to make georeferencing units available as the Leica IPAS20 standalone system for a wide range of airborne sensors such as imaging, LIDAR, synthetic aperture radar (SAR), thermal and multispectral systems.

The Leica Geosystems Leica IPAS20 solution comprises of

reliable, highest-quality hardware components assembled

to strict Leica Geosystems quality specifications and

conforming to international airborne standards. Whether

you invest in a fully integrated system optimized for your

requirements or in individual components to improve the

system you already have, you can be assured that strict

manufacturing quality control and testing has been

exercised throughout the total production chain. Your

business depends on your sensor systems’ reliable opera-

tion and uptime that you have come to be expected from

Leica Geosystems products.

The benefits of the flexible Leica IPAS20 solution, its

modularity and its ease of integration are maximized in a

full system solution by Leica Geosystems. Yet, wishes of

3rd party sensor users can also be satisfied. See the Leica

IPAS20 equipment list for details of system configuration

selections. Leica Geosystems consultation on other

custom configurations is available on request.

Leica IPAS20System integration and optimal workflow

In a complete Leica Geosystems workflow airborne sensor

system is the key for effective airborne sensing projects.

Leica Geosystems has decades of experience in this field

and provides system solutions which are highly integrat-

ed, but also flexible and modular when used as stand-

alone components. The Leica IPAS20 with Leica IPAS TC

and Leica IPAS CO+ permits data acquisition and direct

georeferencing of airborne sensor data and camera orien-

tation. Leica FPES is used for optimized flight planning,

flight evaluation and project management. Leica FCMS

performs flight guidance and sensor control, as well as

in-flight data evaluation, recording and reporting.

The Leica IPAS20 system for all types of airborne sensorsThe Leica IPAS20 system consists of the Leica IPAS20

Control Unit with integrated GNSS receiver, GNSS anten-

na, IMU and software. The Leica IPAS20 Control Unit

allows interfaces to various IMU’s and up to four sensors.

It is designed for all types of airborne sensors such as

film frame cameras, digital frame cameras, line scanners,

LIDAR sensors, SAR or any other airborne sensors.

Leica GNSS technology (GPS and GLONASS)Leica IPAS20 uses state of the art GNSS technology. In

addition to GPS, Leica IPAS20 also tracks GLONASS

satellites. An upgrade to GPS L5 and Galileo will be

available as these systems become operational.

Choice of different IMU typesThe universal plug-and-play IMU interface of the Leica

IPAS system allows the connection of the best IMU choice

for a particular sensor system and application. The IMU is

selected depending on customer requirements for

performance, accuracy, exportability and cost and aided

by the experience of Leica Geosystems. All available IMU

types (different accuracy classes and manufacturers)

have passed Leica Geosystems’ extensive qualification

process before they are released.

Leica RCIF30 interface for RC30 aerial camera system – a Leica ASCOT successor The Leica RCIF30 interface is available for users of the

Leica RC30 aerial camera system. It is side mounted on

the Leica IPAS20 Control Unit and optimally connects the

aerial camera system to the Leica IPAS20 and Leica FCMS.

All components act as one compact system that provides

direct georeferencing, flight guidance and camera control

for Leica RC30 users. This setup is the successor to the

Leica ASCOT for Leica RC30.

Perfect interface to Leica FCMS, Flight & Sensor Control Management SystemThe Leica IPAS20 control unit provides a direct interface

to the Leica FCMS. The Leica Flight & Sensor Control

Management System makes survey flights an easier task

for pilot and operator. It provides in-flight guidance and

sensor control plus in-flight evaluation and completes the

components required for the airborne sensor system.

Precise Point Positioning – PPP Leica IPAS GNSS-IMU systems can benefit from Precise

Point Positioning (PPP) technology without requiring any

specific GNSS hardware. PPP eliminates the necessity to

have a DGPS ground station close to the project area.

System accuracies, when converted to ground coordinates

and considering the GNSS satellite constellations and final

ephemeris data, may result in photo center positional

accuracy of +/- 15 cm rms, or better. The tightly coupled

PPP processing option for GNSS-IMU systems is offered in

Leica IPAS TC.

GNSS-only configuration A Leica IPAS20 without IMU is a cost saving solution for

airborne imagery and photogrammetry projects. This

GNSS-only solution provides precise photo centers after

GNSS data post-processing. Through the acquisition of

precise positional coordinates of the photo centers and

their use in an AT photogrammetric block adjustment, the

number of ground control points (GCP’s) can be reduced

to a few check points. This results in a significant cost

saving in GCP establishment compared to those required

for traditional airborne projects. The investment in the

GNSS-only solution is lower because the IMU is not part of

the system. On the other hand, the full benefits of direct

georeferencing are not available in this cost saving

configuration.

Global service and supportLeica Geosystems provides customized professional

service 24 hours per day, 7 days per week. Service

engineers are available from Leica Geosystems Service

Centers located in all main regions around the world to

processing. Leica IPAS Freebird with IPAS TC allows you to

maintain the quality even for missions with degraded or

disrupted GNSS signal.
