NetAcquire and TENA

Limitations of Traditional Network Telemetry

Networked telemetry, radar, and data acquisition equipment offer many advantages in aerospace data collection applications by breaking distance limitations and supporting simultaneous distribution to multiple locations.

However, traditional network telemetry systems can suffer from significant interoperability problems. Although low-level aspects of network communication commonly utilize standards like Ethernet and TCP/IP, higher-level standards are missing from telemetry applications. These missing standards include data formats, configuration information, and command/status messages.

With each vendor and each user community potentially implementing different high-level interfaces, development costs can quickly escalate when equipment from different vendors must be integrated or when interoperability across organizations is required.

TENA and NetAcquire for a Next Generation Solution

TENA middleware was developed by the U.S. Department of Defense to serve as a advanced foundation for the next generation of network-centric systems.

The combination of TENA middleware and NetAcquire hardware/software systems offers a major enhancement to networked aerospace data collection systems:

  • Standardized, vendor-neutral interfaces to telemetry, radar, and data acquisition systems
  • Pre-engineered and tested middleware available at no-charge to government users
  • Fully distributed network capability, in addition to being backward compatible with most non-networked legacy equipment, such as mid- generation radars
  • Guaranteed real-time performance designed to meet low-latency, deterministic requirements
  • Powerful publish/subscribe data distribution to unlimited network destinations

TENA Background

In order to quickly realize the benefits of next-generation network-centric systems, the telemetry community has needed cross-vendor standards, preferably with low-cost, pre-engineered reference implementations.

The U.S. Department of Defense Central Test and Evaluation Investment Program (CTEIP) has created a new infrastructure for DoD Test and Training Range interoperability in partnership with the user community. The advanced middleware product is called TENA (Test and Training Enabling Architecture).

TENA directly targets the interoperability and reuse needs of networked aerospace applications by defining:

  • A standard mechanism for efficiently communicating structured data (objects) over networks
  • Pre-engineered vendor-neutral interfaces for common aerospace objects as well as a powerful extension mechanism for creating new interfaces.

TENA defines general-purpose objects that represent telemetry – and range – related entities such as radar systems, telemetry feeds, aircraft and other moving objects, and time/space coordinates. For example, a complex operation such as retrieving the real-time coordinates of an aircraft becomes a call to a TENA function such as Aircraft.TSPI.Position(). TENA middleware communicates over any IP network and is available for deployment now.

NetAcquire Background

NetAcquire systems are highly re-configurable, real-time telemetry and data acquisition products. Their field-proven COTS architecture dramatically reduces system cost while at the same time providing straightforward, flexible support for almost any type of I/O signal, data format, and real-time data processing requirement.

NetAcquire products provide TENA middleware with the real-world interfaces necessary to implement a wide range of TENA-compliant solutions and NetAcquire products are all available with a pre-installed TENA middleware option.

NetAcquire products also run a true real-time operating system, which in turn allows TENA to run in guaranteed real-time. This support for low-latency, deterministic system operation opens the door for TENA deployments into the widest possible range of mission-critical aerospace data collection applications.

TENA/NetAcquire Example — A Radar Gateway

Most mid-generation radars lack network capability, requiring communication using legacy serial data protocols and limiting interoperability.

NetAcquire systems provide built-in synchronous serial and digital interfaces for directly connecting to almost any existing radar. Serial data from the radar is ingested, converted into appropriate user coordinates, and published onto any network using TENA.

This allows off-the-shelf PCs to easily access all radar control, status, and target data using convenient function calls supplied by TENA. For example, to point a radar, simply call: Radar.point(azimuth, elevation)

Preston Hauck

President, Chief Technology Officer

Preston Hauck founded NetAcquire in 1993 with the goal of providing computer communications and processing systems that seamlessly operate with real-time performance over distributed networks.

During the early years of NetAcquire, Preston took a hands-on role in developing new products. He remains enthusiastically involved in helping customers solve complex real-world challenges.

As the company grew, Preston leveraged his information systems background to create tools that could automate business processes, increasing company efficiency, responsiveness, and scalability. In his current role, Preston oversees new product direction, manages company growth,works directly with clients and the engineering team on projects that call for his applications design expertise.

Prior to founding NetAcquire, Preston served as vice president of software engineering for Microstar Laboratories, a provider of PC-based test and measurement products. During his tenure, he helped the company grow tenfold in both revenue and employees. Preston developed an innovative real-time operating system from the ground-up, plus a data processing engine that powered all of Microstar's products for more than two decades.

Preston holds a bachelor's degree in computer science, graduating first in his class in 1984 from the University of British Columbia.  He was granted a U.S. patent for developing a novel approach to initialize one processor from another in a multi-processor system. He has published a number of papers on real-time computer systems and regularly teaches networked telemetry processing classes.

Preston was born in Canada. After many years living in Washington State, he proudly became a naturalized U.S. citizen in 2003. He enjoys traveling, reading, photography, basketball, skiing, and movies with his wife Colleen and their two children.

John Bono

Engineering Vice President

John Bono, a Seattle area native, graduated summa cum laude with a Bachelor of Science in Electrical Engineering from the University of Washington.  John started his career with Boeing Aerospace Company, working in a variety of roles. He received personal recognition from Boeing’s CEO for his contributions to 767 avionics.  John designed hardware and firmware for a Mil-Std-1553 bus interface and was the hardware lead and system designer for a B-1B flight simulator’s computer generated imagery display.  After Boeing, John joined Advanced Technology Laboratories (ATL) as a signal processing engineer. He was promoted to the role of ultrasound system architect before becoming the software and systems lead for an image storage and network transport system. During John’s tenure at ATL, he received a Technical Fellow award, became a member of the Senior Technical Staff, and had a role in ATL’s achievement of ISO 9001 certification.  

When John joined the rapidly growing NetAcquire Corporation in 2001, his “big company” experience was leveraged to enhance configuration management and quality systems and processes. He soon became the Management Representative for the company’s AS 9100 certification efforts.  

Today, John is involved in the system, hardware, and firmware design of virtually every system NetAcquire ships.  While the majority of these systems are customer-specified configurations of NetAcquire COTS hardware and software modules, many other systems are rack-sized, challenging configurations involving complex interchanges of information in all forms.  The NetAcquire motto of “connect anything to anything” is John’s daily mission; he knows that, when applied to real-time systems, there will be a continuous stream of interesting problems to solve and challenges to conquer to best meet the needs of his customers and their mission critical projects around the world.
