It seems to be an L1/L2 dual frequency surveying receiver.
Searching for "minimac 2816", without the "AT", seemed to produce a  few 
more results with the following from 1988 amongst them....

 A new portable dual-frequency Global  Positioning System (GPS) receiver is 
being delivered to customers by Aero  Service. The MINI-MAC Model 2816 
receiver is lightweigt, portable, and designed  for operation by one person in 
field environments. The receiver is packaged to  withstand harsh 
environmental conditions and deliver dual-frequency data of the  highest quality. 
Decoded broadcast ephemerides allow for field data. Time and  pseudoranges 
obtained via the unit’s coarse/acquisition (C/A) code L1 capability  are used to 
obtain precise time synchronization. The receivers record on  canonical times, 
so it is not necessary to start different receivers at the same  time in 
order to maintain synchronous phase observations. The MINI-MAC 2816  Surveyor 
is capable of tracking up to eight satellites simultaneously using C/A  code 
on L1 and Aero’s proven proprietary codeless methods on L2. An L1-only  
version, Model 1816, is also available. Phase lock can be maintained on up to  
eight satellites in kinematic operations. The receiver is designed for 
future  implementation of kinematic software without any required hardware 
changes.  Various aspects of the receiver are discussed and details of a number of 
field  results are provided.
