Q&A with | Parker LORD Microstrain Sensing

Let’s talk about the new navigation system from MicroStrain, the 3DMGQ7-GNSS/INS with RTK.

Our new all-in-one navigation system with onboard RTK and built-in dual antenna GNSS receivers is a complete out-of-the-box solution at a very competitive price. This advanced inertial navigation system includes:

A. The 3DMGQ7-GNSS/INS which can achieve centimeter-level position accuracy when paired with our 3DMRTK. It has dual multiband GNSS receivers, low noise and low drift MEMS inertial sensors, and a robust adaptive Kalman filter.


 

B. The 3DMRTK provides easy to use real time Kinematic (RTK) correction data to be utilized by the 3DMGQ7-GNSS/INS. It provides the simplicity of a cellular connection to our SensorCloud RTK base station network, replacing traditional radio-based stations. With RTK corrections the 3DMGQ7 can achieve centimeter-level positional accuracy. By removing the need for base station infrastructure, the 3DMRTK minimizes the user’s required time to market.

C. SensorCloud RTK provides seamless cloud-based network RTK corrections without the need for customer-supplied base stations and includes a cellular data plan with network RTK coverage. 

D. Access to MicroStrain software:

  • SensorConnect PC Software for sensor configuration and data collection.
  • MSCL The MicroStrain Communication Library simplifies writing code to interact with our sensors.
  • ROS License-free drivers for the Robot Operating System.

 

What are the key upgrades over other inertial navigation solutions?

Position
RTK corrected to 2 cm
Single point, horizontal @ 1.25 m
Single point, vertical @ 2 m

Attitude
Roll, Pitch @ .05°
Heading @ .25°

Dynamic
Velocity @ 0.05 m/s

Low Profile
76 mm x 68.6 mm x 13.3 mm and lightweight at 78 grams

What applications do you see utilizing this inertial navigation solution?

  • Autonomous vehicle (AV) operation
  • Wheeled and legged robotics
  • Simultaneous localization and mapping (SLAM)
  • Beyond visual line of sight (BVLOS) navigation

 

Can you share with us an example of this sensor being utilized currently?

This video shows the GQ7 and RTK modem being used on an AM General High Mobility Multipurpose Wheeled Vehicle, a Clearpath Robotics Unmanned Ground Vehicle (UGV), and an aerial drone.

 

What was your team's focus when designing this new inertial navigation system?

To provide a solution that offers ease of use and eliminate the customer’s need to outsource components and programming. The integration of our MSCL (MicroStrain Communication Library), ROS, and several Open-Source API’s, allows for the application of available and compatible software. Cost was also important as we understand the positive impact of an affordable solution. We also focused on ways to reduce the user’s costly programing time, and with the inclusion of our software and API’s believe that this is the best navigation product available.

 

How were you able to keep your product priced significantly lower than the competition?

While we are in business to produce and sell products, we also believe in establishing long-term and quality customer relationships. Our highly experienced team of scientists and engineers, and our relationships with vendors to get early access to the next generation of sensors and components before they are released, as well as our state of the art supply chain allows for significantly reduced prices. Customer satisfaction and customer success is very valuable to us. Parker LORD MicroStrain has been in the sensor business for over 20 years. With experienced engineers, developers and manufacturers, we are able to provide a solid, reliable solution. Combining current technology advancement, our core competency in calibration and miniaturization and our close relationship with MEMS vendors, allows for pricing that our customers find very affordable.

 

Is there anything else Parker LORD has in the works that you would like to mention?  New products?  Upcoming events?

Our Parker LORD merger provides collaboration leading to cutting edge products in the future. Our 7th generation solutions are in development as we once again push the limits of technology, offering a sophisticated and reliable sensing solution. Look for another Parker LORD Webinar in the near future to showcase and demonstrate the success of our sensors in various applications as well as addressing potential areas of applications that would benefit from this solution. MicroStrain’s products have always been reliable, affordable, and interchangeable.

Benefits of a Tactical Grade IMU in Low-cost GNSS/INS Systems
When determining which system is right for your application, it can be difficult to visualize the impact of IMU selection on total system performance. Our goal in this paper is to show how the quality of the IMU affects the end-use system via several real-world tests.
Better Data equals Better Navigation
To achieve navigation accuracy, sensors use algorithms that look at a series of measurements (as opposed to a single measurement) and generate output numbers that compensate for measurement errors. These algorithms are known as sensor fusion algorithms or Kalman filtering.

GNSS and INS performance accuracy is generally tested in an ideal static environment, and often not representative of end use performance. Dynamic environments introduce error sources such as multipath, obscured sky view, vibration, inconsistent RTK data streams and more.

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
