A GNSS hostile environment simulator for accurate real-time processor & hardware in the loop (PHIL) simulations of a multiple antenna GNSSR/AJ system models antenna effects over the entire signal bandwidth allowing direct injection of the RF into the GNSSR. Computational efficiency is achieved by applying the antenna patterns in the frequency domain. To preserve the integrity of the antenna signals, the transmitter signals are generated over an extended period to push any residual ringing outside the update window. Efficiency is further enhanced by using a combination of single-precision and double-precision floating-point units to generate the samples of the transmitter signals with single-precision floating-point. All subsequent calculations are then computed in single-precision.

An Instrumented Spherical Blast Impulse Recording Device (ISBIRD) provides for survivable test measurement of an explosive blast impulse. The ISBIRD includes a spherical housing formed of a metal having a thickness sufficient to survive the explosive blast wave from a test weapon. A test data module of the ISBIRD includes: (i) a three-axis acceleration sensor; (ii) a memory; and (iii) a controller communicatively coupled to the three-axis acceleration sensor and the memory. The controller executes a data acquisition utility to record acceleration data in three-dimensions from the three-axis acceleration sensor during exposure of the spherical housing to the explosive blast wave. An internal support structure of the ISBIRD is attached inside of the spherical housing and attached to the test data module. The internal support structure centrally locates the test data module within the spherical housing during exposure to the explosive blast wave.

A system for determining a location in a disadvantaged signal environment includes three aerial vehicles hovering at high altitude and spaced apart to form a triangle, and a mother aerial vehicle positioned a distance away and at a lower altitude. The mother aerial vehicle acquires and transmits coarse geolocation information, using a pulse compression, high-power X Band radar and directional antenna, to each of the three aerial vehicles to direct them to coarse geo-positions above designated respective ground locations. One of the three aerial vehicles has a synthetic aperture radar for producing a terrain strip-map that is mensurated against a map database to provide fine position adjustments for each of the three aerial vehicles, which are also also configured to transmit a respective signal coded with its latitude, longitude, and altitude, for a computing device to perform time difference of arrival measurements of the signals to determine its location.
