The Klas Pioneer Express (GRRIP, AN/PSC-15) is the lightest, fully featured, mobile SIPRNET case designed for the first-in communicator. It weighs less than 28lbs and all the components fit in a single, ruggedized case measuring 16″ x 13″ x 6.87″. The Klas Pioneer Express, or GRRIP (Global Rapid Response Information Package), has a 3 hour battery and accepts a wide range of AC and DC inputs. It is quick to setup and is designed around standard applications such as Microsoft Outlook. It has everything you need to deploy a mobile office to the field including a laptop, red-side router, black-side router, TCP accelerator, phone handset and battery. It supports the Talon type 1 encryption PCMCIA card, the SecNet54 type 1 encryption module, and includes a BGAN satellite phone for remote operation at broadband speeds. Over 2,000 GRRIP systems have been fielded by U.S. DoD organizations. Most recently, the Army has deployed many systems to keep the coalition network running during the retrograde of forces in Afghanistan.

The Pioneer Express (GRRIP / AN/PSC-15) Set-up wizard enables an untrained operator to entirely configure a kit whose encryption device has become zeroized in the field. Using a simple step-by-step approach the Wizard guides the operator through the entire reconfiguration process. Using its own database and calculations the Wizard instructs the operator exactly what to enter in what field as they appear on screen. This puts the technical support right inside the kit, where operators can most easily access it.


Secure satellite connections can be a challenging environment for the TCP/IP protocol. Long latencies and jittery bundling of packets can seriously reduce the potential bandwidth a TCP/IP link can establish. This makes the use of acceleration, HTTP pre-fetch and compression technologies vital for the effective functioning of the Klas Pioneer Express (GRRIP,AN/PSC-15) unit. These technologies work together to let standard TCP/IP applications work as if they were connected to an office network.


Space Communications Protocol Standards (SCPS)

KlasRouter provides SCPS compliant TCP acceleration based on MITRE’s implementation of the SCPS-TP protocol. KlasRouter supports both vendor-independent SCPS mode and Klas optimized SCPS mode to interoperate with any SCPS-compliant Service Entry Point hardware (such as ViaSat xPEP and Comtech EF Data turboIP). In Klas optimized SCPS mode, Klas has modified and improved the MITRE implementation to mitigate Inmarsat BGAN specific conditions such as high jitter and varying bandwidth availability. This customization provides optimum performance for TCP-based applications such as web and email.

HighSpeed TCP (HS-TCP)

KlasRouter supports the HS-TCP algorithm as developed by Sally Flood and adopted by the Internet Engineering Task Force. HS-TCP is implemented in Performance Enhancing Proxy (PEP) mode on KlasRouter in a similar way to SCPS and is therefore transparent to the network.

In addition to the required WAN optimization features, KlasRouter includes the following advanced WAN optimization components as optional features which otherwise would require separate hardware. These value added features exceed the specification and are included at no additional cost to the Government.

HTTP Caching

Layer 3/4 acceleration using SCPS or HS-TCP is a critical part of WAN Acceleration. However, the performance of higher layer protocols such as web-based applications also is degraded over satellite. KlasRouter implements HTTP web caching and pre-fetch to mitigate the effects of network latency. This algorithm has been employed with excellent results on SIPRNet and JWICS web applications such as Outlook Web Access, AKO-S, CIDNE, CHAMPION and various other intelligence-specific cloud-based services.

HTTP objects are cached locally for re-use to avoid repeat download of the same web page across satellite. This feature is particularly useful in a multi-user environment where the same web pages are likely to be requested by different users. When first accessed, a HTTP object such as an image is saved on KlasRouter to be made available should another user request the same object. In such case, the KlasRouter supplies the cached object rather than traversing the satellite link to the web server to download a duplicate copy. This substantially improves performance while reducing costs. However cache coherency is maintained at all times to prevent out-of-date objects from being presented from the cache.


The high latency on BGAN and other satellite networks causes the initial load of each web page to be slowed markedly. A page that takes 2-3 seconds to load over a low latency network can take 30 seconds to load over a high latency network. KlasRouter mitigates this by scanning each downloaded web page for links to other pages. Since it is likely that the user will select one of the links on the page, KlasRouter downloads the text of each linked page automatically in the background. When the user selects a link, the text of the linked page is served from local KlasRouter cache providing instantaneous page load. Note that images and other large HTTP objects are not pre-fetched as this would increase costs by downloading large amounts of data that may not be used. Instead, these objects are loaded after the text of the page is presented.

It includes a RedSide Router and BlackSide Router, enabling a secure and unsecure network enclave operate off the GRRIP simultaneously. This section describes the data flow of these networks in the Klas Pioneer Express (GRRIP,AN/PSC-15) and the different network ports they present an operator.

Data Flow when used with KOV-26 Talon

The GRRIP system has undergone TEMPEST, JITC certification and MILSPEC 810F testing. It supports the L3 TALON/KOV-26 and Harris SecNet-54/KIV-54 Type 1 encryption devices.

The Klas Pioneer Express’s (GRRIP, AN/PSC-15) auto-sensing, auto-switching power system allows for continuous operation of the kit even from unreliable power sources. Accepting a wide range of AC and DC inputs (110-230V AC, 10-36V DC)

The kit can be connected to solar panels, noisy diesel generators, 12V/10A car sockets, BB 2590, BA 5590 and nearly any other source of power that can be located in the field. The kits Uninterruptible Power Supply (UPS) with Auto Changeover automatically changes over from one power source to another when that power source fails. It will ultimately utilize the kits own internal three hour battery if all other sources fail. This all occurs without the need of any operator input.

Every component in the GRRIP has been designed to require very little power to run. The result is a 40-50 Watt power footprint that makes it easily the most power efficient system in the market.




The Klas Pioneer Express (GRRIP, AN/PSC-15) can be used in both a tactical and urban environment. By utilizing both commercial and Government Satcom like BGAN, VSAT or X-Band as well as locally available terrestrial IP connections like hotel broadband, WiFi and cellphone 3G the Klas Pioneer Express (GRRIP, AN/PSC-15) provides a communicator with an extremely versatile reach back capability. Any network, anywhere can now be used to send secure voice, data, photos and video.
