solys2 0.1.12

Solys2 interface and automatic tracking functions.

solys2

Python package for connecting and communicating with the Solys 2 via TCP/IP and setting it up to automatically track the moon or the sun.

Requirements

python>=3.8 numpy>=1.22.2 pylunar>=0.6.0 pysolar>=0.10 ephem>=4.1.3 spicedmoon>=0.1.2 spicedsun>=0.0.1

Installation

pip install solys2

Usage

Direct communication

from solys2 import solys2

# Connect with the Solys2
solys = solys2.Solys2(ip, port, password)

# Tell the Solys2 to point at azimuth 30.
solys.set_azimuth(30)

# Get the current position at which the solys is pointing.
az, ze, _ = solys.get_current_position()

# Send the command "HO" to the Solys2
output = solys.send_command("HO")
# Another option would have been calling solys.home()

Automatic tracking

from solys2 import autotrack

# Track the sun, sending a new position each 15 seconds, and logging the
# information (movements, etc) to a file called "solys.log"
st = autotrack.SunTracker(ip, 15, port, password, True, "solys.log")

# Stop tracking the Sun
st.stop_tracking()

SPICE

Kernels

In order to use the SPICE libraries, a directory with all the kernels must be specified.

That directory must contain the following kernels:

• https://naif.jpl.nasa.gov/pub/naif/JUNO/kernels/spk/de421.bsp
• https://naif.jpl.nasa.gov/pub/naif/pds/wgc/kernels/pck/earth_070425_370426_predict.bpc
