\u00a0Gen I<\/a>\u00a0and Gen II systems will eventually be fielded to 20,000 vehicles (like Abrams, Strykers, Bradleys and some Joint Light Tactical Vehicles), leaving approximately 150,000 tactical vehicles without the added capability.<\/p>\n\u201cThere are no fuel haulers in the program of record. There are no ammunition vehicles. There are no ambulances [and] command and control nodes aren\u2019t included,\u201d Mebust said during a March 24 interview. \u201cIf you look at not only the entire kill chain \u2026 the support missions that are required to keep the army moving, but none of those are also covered under the current program of record.<\/p>\n
\u201cThe Abrams doesn\u2019t do very well without ammunition [and the] Bradley does not do very well without fuel. So how does a fueler meet up with a Bradley in a contested environment if it doesn\u2019t have GPS [and] it can\u2019t calculate a route?\u201d he added.<\/p>\n
Although the Army currently does not have a requirement to provide those additional vehicles with APNT systems, General Dynamics has built out three potential packages and showed them in action to the service. At the crux of the plan is a lower price point than the $40,000 and $45,000 it costs the Army to outfit each vehicle with MAPS Gen I, Mebust said.<\/p>\n
More specifically, all three technology packages are designed to be \u201cdropped in\u201d (i.e., the\u00a0DAGR is pulled out while the other brackets, mounts and cables remain in place),\u00a0range in price from $1,800 up to $30,000, and are designed for different threat sets.<\/p>\n
\u201cCondition one is a little bit of noise, it can be mitigated quite easily,\u201d Mebust said.\u00a0\u201cIn condition number two, there\u2019s a lot more noise and the spoofing threats begin to appear, so now you\u2019re going to need an anti-jam antenna to mitigate those threats.<\/p>\n
\u201cFor condition three\u2026there will come a point for any system where you will no longer be able to get GPS [because] there is so much interference in the environment and you will simply not be able to hear the satellites,\u201d he added.<\/p>\n
For the lower end of that threat spectrum, the company is offering up the \u201cHorizon Nuller\u201d package, which includes either the legacy DAGR or the Enhanced D3 (ED3M) distribution hub paired with a modified reception pattern antenna (MRPA) currently being used in Eastern Europe, he explained.<\/p>\n
\u201cThere\u2019s nothing fancy, there\u2019s no electronics or software. This is a mechanical solution, and it is a drop-in replacement for current antennas on vehicles,\u201d Mebust said.<\/p>\n
For vehicles that may need a layer of protection against spoofing, General Dynamics has built the \u201cFight Tonight\u201d package that includes an EDM3M, possibly with the Victory\u00a0CSAC Accessory Module (VCAM), that is then paired with either Raytheon\u2019s Landshield \u201canti-jammer\u201d or NovAtel\u2019s GAJT-410ML anti-jam technology.<\/p>\n
\u201cThey\u2019re able to block the noise coming from an emitter,\u201d Mebust said. \u201cIf there\u2019s a jammer out there [and] it\u2019s really pumping a lot of [radio frequency] RF energy at you\u2026it\u2019ll basically tone that down, so you\u2019ll be able to hear [the] GPS.\u201d<\/p>\n
Pricing for this middle tier package starts around $30,000, and it\u2019s currently\u00a0fielded in the Indo-Pacific region with Patriot units.<\/p>\n
And finally, to provide vehicles with enhanced protection, the company is developing a Highly Assured Location and Orientation, or Halo System package that it anticipates will be ready for production by the end of 2023 and carry a $20,000 price tag. That package includes the ED3M\/VCAM with the Halo Line Replaceable Unit, a five-element anti-jam antenna. The company claims this will provide vehicles with a higher\u00a0level of protection against jamming and spoofing by enabling troops to access a second source of PNT via a different satellite constellation.<\/p>\n
Although the company is billing this family of packages as a complement to MAPS, it is also eyeing the US Marine Corps as a customer, and is interested in that service\u2019s Mounted Assured Resilient Navigation requirement.<\/p>\n
