  The fifth Sloan Digital Sky Survey (SDSS-V) Local Volume Mapper (LVM) is a
wide-field integral field unit (IFU) survey that uses an array of four 160 mm
fixed telescopes with siderostats to minimize the number of moving parts.
Individual telescope observes the science field or calibration field
independently and is synchronized with the science exposure. We developed the
LVM Acquisition and Guiding Package (LVMAGP) optimized telescope control
software program for LVM observations, which can simultaneously control four
focusers, three K-mirrors, one fiber selector, four mounts (siderostats), and
seven guide cameras. This software is built on a hierarchical architecture and
the SDSS framework and provides three key sequences: autofocus, field
acquisition, and autoguide. We designed and fabricated a proto-model siderostat
to test the telescope pointing model and LVMAGP software. The mirrors of the
proto-model were designed as an isogrid open-back type, which reduced the
weight by 46% and enabled reaching thermal equilibrium quickly. Additionally,
deflection due to bolting torque, self-gravity, and thermal deformation was
simulated, and the maximum scatter of the pointing model induced by the tilt of
optomechanics was predicted to be $4'.4$, which can be compensated for by the
field acquisition sequence. We performed a real sky test of LVMAGP with the
proto-model siderostat and obtained field acquisition and autoguide accuracies
of $0''.38$ and $1''.5$, respectively. It met all requirements except for the
autoguide specification, which will be resolved by more precise alignment among
the hardware components at Las Campanas Observatory.
