hackrf vs bladerf vs others?

Can say for sure because I don’t have access to a room the size you mention and can’t find where you found the range of it but I recon that a hack rf in the middle of the 80meter room (if shielded so no interference) would do the trick

The HackRF doesn't have an onboard clock that is accurate enough to simulate/spoof GPS signals.  However, this can be done by buying a cheap external clock that plugs into the HackRF board inputs. Ebay has tons of Chinese sellers who advertise these for very cheap(around $15).

You could buy an Ettus USRP B200 or B210 for around $1,216, A bladeRF x40 for $420, or a LimeSDR for $299.  LimeSDR is full-duplex, MIMO, and superior to BladeRF. The LimeSDR even matches much of the USRP's B210 specs. The only (temporary) drawback to the LimeSDR is that it doesn't have the same level of software support as the USRP.  However, LimeSDR is completely open source and software development is moving very fast.
