  The Gamma-Ray Burst Monitor (GBM) on the {\it Fermi Gamma-Ray Space
Telescope}, for the first time, detected a short gamma ray burst (SGRB) signal
that accompanies a gravitational wave signal GW170817 in 2017. The detection
and localization of the gravitational wave and gamma-ray source led all other
space- and ground-based observatories to measure its kilonova and afterglow
across the electromagnetic spectrum, which started a new era in astronomy, the
so-called multi-messenger astronomy. Therefore, localizations of short
gamma-ray bursts, as counterparts of verified gravitational waves, is of
crucial importance since this will allow observatories to measure the kilonovae
and afterglows associated with these explosions. Our results show that, an
automated network of observatories, such as the Stellar Observations Network
Group (SONG), can be coupled with an interconnected multi-hop array of CubeSats
for transients (IMPACT) to localize SGRBs. IMPACT is a mega-constellation of
$\sim$80 CubeSats, each of which is equipped with gamma-ray detectors with
ultra-high temporal resolution to conduct full sky surveys in an energy range
of 50-300 keV and downlink the required data promptly for high accuracy
localization of the detected SGRB to a ground station. Additionally, we analyze
propagation and transmission delays from receipt of a SGRB signal to ground
station offload to consider the effects of constellation design, link, and
network parameters such as satellites per plane, data rate, and coding gain
from erasure correcting codes among others. IMPACT will provide near-real-time
localization of SGRBs with a total delay of $\sim$5 s, and will enable SONG
telescopes to join the efforts to pursue multi-messenger astronomy and help
decipher the underlying physics of these events.
